These sets of worksheets will help your students practice combining variables within algebraic expressions.

Two like math terms have the same variables. This could be the base number or variable. It could also be a base variable that has the same exponent. As we advance with this skill, we will learn that coefficients can be different in like terms. For example, the value -4yz2 and yz2/3 are like terms. In order to solve equations and expression, you will combine like terms often. Often it the first step to solve just about anything in algebra. Be sure that you carry any math operator that is attached to the term. For example: 4y + 7x - 5y + 3x. The 5y carries the negative operator with it. When we combine this, we will end up with -1y + 10x. I like to urge students to underline like terms. If you have two like terms that involve the variable x and y, I would have them underline the x terms once. This would be followed by underlining the y terms twice.

Your students will use this collection of activity sheets to learn how to solve for variables to simplify algebraic expressions. These sets of worksheets introduce your students to the concept of combining like terms, and provide examples, short practice sets, longer sets of questions, and quizzes. This is a paramount skill in algebra, you will need to master it in order to have an easy transition to higher level math. You basically cleaning up an expression or equation to just make it more workable. We suggest whenever you are evaluating expressions or equations to think about like terms first. This series of lessons and worksheets teach the steps for simplifying equations by matching or combining terms that are alike until there are no more steps that can be performed. A variety of equations are provided ranging from simple to advanced.
