Answer:
x = -5
Step-by-step explanation:
6x + 2x + 13 = 3x-12
Combine like terms
8x+13 = 3x-12
Subtract 8x from each side
8x-8x+13 = 3x-8x-12
13 = -5x-12
Add 12 to each side
13+12=-5x-12+12
25 = -5x
Divide by -5
25/-5 = -5x/-5
-5 =x
Answer:
Part A
Add Like terms
6x + 2x + 13 = 3x - 12
8x + 13 = 3x - 12
get x on the left side
5x + 13 = -12
Subtract 13 from both sides
5x = -13 -12
5x = -25
Divide both sides by 5
x = -5
