Substitute:

Answer:
x=25
Step-by-step explanation:
First, we add all like terms. Then, we solve for x.

We can rearrange some things because order does not matter with addition. Next, we just use basic equation solving techniques.
For -4+2, plot -4, then move to the right 2 spaces. You should land on -2.
For -4+(-2), plot -4 then move the left 2 spaces. You should land on -6.
