Voila! We have solved our first algebra equation! Remember, the goal is to get the variable alone by doing the same thing to each side of the equation. With this you have a good understanding of basic algebra, and now you should be able to solve other equations like 6 + k = 11 or 11 - m = 7. Otherwise, you may want to re-read this lesson.

Take the solution(s) and put them in the original equation to see if they really work. Example: solve for x: 2xx − 3 + 3 = 6x − 3 (x≠3) We have said x≠3 to avoid a division by zero. Let's multiply through by (x − 3): 2x + 3(x−3) = 6. Bring the 6 to the left: 2x + 3(x−3) − 6 = 0. Expand and solve:
Equation Basics Lesson Brush up on your knowledge of the techniques needed to solve problems on this page. Equation Calculator Will automatically solve equations and show all of the required work.
When solving a simple equation, think of the equation as a balance, with the equals sign (=) being the fulcrum or center. Thus, if you do something to one side of the equation, you must do the same thing to the other side. Doing the same thing to both sides of the equation (say, adding 3 to each side) keeps the equation balanced.
3. Simple Equations: Solving for the Unknown. An equation is like a statement that says two things are equal. It has two sides, usually separated by an equal sign (=). The goal of algebra is often to solve equations, which means finding the value of the variable. Basic Equation Example. Let’s go back to our earlier equation: x + 3 = 7

4. Solving Equations, like this one: 5 − (x + 2) = 5x. 5. Formulas and Literal Equations, which shows how to solve an equation for a particular variable. 6. Applied Verbal Problems shows why we are doing all this. What is Algebra? Algebra is the branch of mathematics that uses letters in place of some unknown numbers.
An equation is something that contains two quantities separated by an equal sign; the two quantities are equal but are represented differently (e.g. 2+2 = 4). An algebraic equation contains at least one variable that is unknown (e.g. 2+y = 4). This section explains the basics of equations and how to keep them balanced.
