To solve the equation x + 8 = 12, you must get x by itself on one side. Therefore, subtract 8 from both sides. To check your answer, simply plug your answer into the equation: Example 2. Solve for y. y – 9 = 25. To solve this equation, you must get y by itself on one side. Therefore, add 9 to both sides.
Learn to solve for a variable in a simple equation An equation is a mathematical sentence that expresses two equal values. In algebra, you'll often work with equations that have an unknown value represented by a variable, or letter. ... Solving an equation means finding the unknown value. The equation may also have a coefficient, which is a ...
Simple equations are mathematical statements that consist of an equal sign (=) and usually contain one variable. These equations are easy to solve and find the value of the variable that makes the equation true. Example: x + 3 = 7 is a simple equation, where “x” is the variable, and solving it would give “x = 4” as the answer.
Solving equations. Here you will learn about solving equations, including linear and quadratic algebraic equations, and how to solve them. Students will first learn about solving equations in grade 8 as a part of expressions and equations, and again in high school as a part of reasoning with equations and inequalities.. Every week, we teach lessons on solving equations to students in schools ...
Equations can be simple to complex, involving fractions, decimals, or integers. The ultimate goal is to determine the values of two variables, like x or y, making the two sides of the equation equal. ... Common Mistakes to Avoid in Solving Equations. Mistakes can happen quickly when working with equations, especially if small steps or details ...

When solving an equation it is important to find the value of one letter. Let's solve the equation 3 x + 4 = 10 To remove the + 4 we complete the inverse (opposite) operation by subtracting the 4.
The equations section lets you solve an equation or system of equations. You can usually find the exact answer or, if necessary, a numerical answer to almost any accuracy you require. The inequalities section lets you solve an inequality or a system of inequalities for a single variable. You can also plot inequalities in two variables.
Solving an equation that is a radical involves a few steps. Express the given radical equation in terms of the index of the radical and balance the equation. Solve for the variable. Consider √(x+1) = 4. Now square both the sides to balance it. [ √(x+1)] 2 = 4 2 (x+1) = 16. Thus x = 16-1 =15. Important Notes on Solving Equations:
Struggling with solving simple equations? In this video, we break it down step by step, making it easy to understand! Learn how to solve basic algebraic equa...
Rational equations are simple equations that include at least one fraction. These simple equations can include one or more operations, too, and require one or more steps to solve. For instance, the simple equation 3/8 + 1/8 = 1/2 contains all fractions with only an addition operation.
There are two sides to an equation, with the left side being equal to the right side.. Equations will often involve algebra and contain unknowns (variables) which we often represent with letters such as x or y.. We can solve simple equations and more complicated equations to work out the value of these unknowns; they could involve fractions, decimals or integers.
In simple words, to solve an equation is to isolate by making its coefficient equal to 1. Whatever you do to one side of an equation, do the same to the opposite side of the equation. Solve equations by adding. Let’s see a few examples below to understand this concept. ...
Simple equation is a linear equation in one variable. Solving simple equation means find the value of the variable. To find the value of the variable, the variable has to isolated. To isolate the variable in a simple equation, you have to get rid of all the values around the variable using one or more of the following properties of equality.
Steps To Solve Simple Equations. Solving simple equations is an essential part of basic algebra. Equations with variables can be solved in just a few steps. Consider The Inverse. It’s important to remember that solving simple equations requires the use of inverse operations. This means you’ll need to use addition/subtraction and ...
To solve simple equations, start by thinking about what’s happening to the variable. About Pricing Login GET STARTED About Pricing Login. Step-by-step math courses covering Pre-Algebra through Calculus 3. GET STARTED. How to solve simple equations Solving simple equations: Just undo everything that's been done! ...
Solving a linear equation like x + 3 = 5 requires that you isolate the variable; in this example, that means subtracting the 3 over to the other side. ... without the "minus" sign on it). And this has also converted the original equation into a simple one-step equation. I'll get rid of the 2 from the left-hand side by "subtracting it over to ...
Solving simple equations. Remember that when you transpose formulas, whatever you do to one side, you must do to the other. If you add, subtract, multiply or divide one side of the equation by a number, you must do the same to the other side. This keeps the equation balanced, or preserves equality. Example 1 – solving simple equations. Solve ...
