# How do you combine (a-2) - (5-3a)?

May 28, 2018

$4 a - 7$

#### Explanation:

Let's distribute the negative to both terms in the second set of parenthesis. We now have

$a - 2 - 5 + 3 a$

Now we can combine like terms. Constants go with constants, and variables go with variables. Thus, we get

$4 a - 7$
