Question

3x - 4 - 5x +7
I have to combine like terms

Answer 1

-2x + 3

Explanation:

Like terms are categorized by the variables (letters) beside them.

It is a pretty simple process. To make it easier, first group the "like terms" together:

( 3x - 5x ) + ( + 7 - 4 )

Then solve the parenthesis:

( -2x ) + ( 3 )

That is it!
