Examples of How to Combine Like Terms with or without the Distributive Property. Now, let’s take a look at some examples! Example 1: Simplify the expression below by combining like terms. There are four terms in this algebraic expression. Two terms with similar [latex]x[/latex]-variables, [latex]3x[/latex] and [latex]7x[/latex], and two ...
The rule for combining like terms states that you can only add or subtract terms with the same variable and exponent. To combine them, simply add or subtract their coefficients while keeping the variable and exponent unchanged. What is important to know about combining like terms?
These terms are like terms, and are combined by adding their coefficients, to get 3x. Take your time, and make sure you are keeping straight in your head how multiplication works, versus how addition works. In fact, "combining like terms" is a topic for which it would be difficult to do "too much" practice. Do as many practice problems as you can.
Example 3. Classify each of the following pairs as either like terms or unlike terms: (a) 3x and −7x, (b) 2y and 3y 2, (c) −3t and 5u, and (d) −4a 3 and 3a 3.. Solution. Like terms must have identical variable parts.. 3x and −7x have identical variable parts. They are “like terms.” 2y and 3y 2 do not have identical variable parts (the exponents differ). They are “unlike terms.”
Like terms are combined in algebraic expression so that the result of the expression can be calculated with ease. For example, 7xy + 6y + 6xy is an algebraic equation whose terms are 7xy and 6xy. Therefore, this expression can be simplified by combining like terms as 7xy + 6xy + 6y = 13xy + y.
Like terms, are terms whose variables (including any exponents) are the same. 2x 5 and 6x 5 are like terms 7a 6 and 3a 5 are NOT like terms Combined: 2x 5 + 6x 5 = 8x 5 7a 6 + 3a 5 = 7a 6 + 3a 5 (cannot combine) Note: while an expression such as 3x 3 + 2x 2 + 5x + 8 uses only the variable letter "x",

Combining like terms. Combining like terms refers to the process of simplifying expressions by adding or subtracting variables and their coefficients. Terms are said to be "like" if they have the same variable and exponent. The expression below shows two different terms that are unlike: Because the terms are unlike, they cannot be added together.
Exponents and Bases: You may have noticed that like terms always have the same base and exponent. Regarding Coefficients: Also, the coefficient in front of a variable does not change whether or not terms are alike. For instance 3x and 5x and 11x are all like terms. The coefficients ( the '3' in 3x, '5' in 5x and '11' in 11x) do not have anything at all to do with whether or not the terms are like.
Combining Like Terms Like terms may be combined by adding or subtracting their coefficients and affixing the result to the common variable. Sample Set A. Simplify each expression by combining like terms. \(2m + 6m - 4m\). All three terms are alike. Combine their coefficients and affix this result to \(m\): 2 + 6 - 4 = 4.
You need to simplify (combine like terms) and then use the same steps as a multi-step equation. 9x + 11 – 5x + 10 = -15 9x – 5x = 4x 11 + 10 = 21 1st – combine like terms 4x + 21 = -15 Now it looks like a multistep equation that we already did -21 -21 Use subtraction to get rid of the addition.
Following the rule that the final answer should use as few symbols as possible, ... In Exercises 1-16, combine like terms by first using the distributive property to factor out the common variable part, and then simplifying. 1. 17xy 2 + 18xy 2 + 20xy 2. 2. 13xy − 3xy + xy.
Like terms are terms that have the same exponent AND the same variable or variables. For example, \(2x\) and \(–5x\) are like terms, and \(3y^2\) and \(y^2\) are like terms. Combining like terms is a way of simplifying an algebraic expression or equation. In the lesson below, we will see a few examples of how this works! [adsenseWide]
Like terms are terms that have the literal coefficients, also known as a variable, the same.The numerical coefficient, that is the number on the left side of the literal coefficient, doesn't need to be the same. In short, having like terms always based on its literal coefficients. It is said to be collected, to simplify expressions in Algebra.
When combining like terms it is important to preserve the equality of the equation by only combining like terms on one side at a time. We will simplify the left hand side first. The first step is to find pairs of like terms, the second step is to add. The x and 3x are like terms, so they are added resulting in 4x. (HINT: when a variable such as ...
Combining like terms is an important skill for simplifying math problems and solving more complex algebra problems later on in your studies. But first: what are like terms? In any mathematical expression, like terms are terms that have identical variable parts. What this means is that they have the same variable(s) raised to the same non ...
Combining like terms will simplify a math problem and is also the proper form for writing a polynomial. To combine like terms, just add the coefficients of each like term. ... Rules & Examples ...
Then we will subtract 7 and 4 that is in front of the y terms. 3x + 5x + 7y + 9x - 4y = 17x + 3y Here are a few more examples: 1.) 7m + 14m - 6n - 5n + 2m Step 1: Organize your like terms. You can use a highlighter, shapes, or just rewrite the problem so that the like terms are next to each other. 7m + 14m - 6n - 5n + 2m Step 2: Combine the ...
