-3x + 7x = -12
(-3 + 7)x = -12
4x = -12 (divide 4 from each side)
4x/4 = -12/4
x = -12/4
x = 3 <-answer

-3 + 7x = -12

simplify -3x + 7x to get 4x. / Your problem should look like: 4x = -12
Second,
divide both sides by 4. / Your problem should look like: x =
Third,
simplify
to 3. / Your problem should look like: x = -3
Answer:
