anonymous · Answer

$$\huge Remember $$
Combining Like Terms is a process used to simplify an expression or an equation using addition and subtraction of the coefficients of terms. Consider the expression below

5 + 7
By adding 5 and 7, you can easily find that the expression is equivalent to

12
What Does Combining Like Terms Do?

Algebraic expressions can be simplified like the example above by Combining Like Terms. Consider the algebraic expression below:

12x + 7 + 5x
As you will soon learn, 12x and 5x are like terms. Therefore the coefficients, 12 and 5, can be added. This is a simple example of Combining Like Terms.

17x + 7
