Simplifying Expressions: Combining Like Terms

Front

What are like terms in an algebraic expression?

Back

Like terms are terms that have the same variable raised to the same power. For example, 3x and 5x are like terms, while 3x and 4y are not.

How do you combine like terms in an expression?

Back

To combine like terms, you add or subtract the coefficients of the terms that have the same variable. For example, in the expression 2x + 3x, you combine them to get 5x.
