-4%28x%2B1%29-9=-12%2B11 Start with the given equation.


-4x-4-9=-12%2B11 Distribute.


-4x-13=-12%2B11 Combine like terms on the left side.


-4x-13=-1 Combine like terms on the right side.


-4x=-1%2B13 Add 13 to both sides.


-4x=12 Combine like terms on the right side.


x=%2812%29%2F%28-4%29 Divide both sides by -4 to isolate x.


x=-3 Reduce.

-4(x + 1) - 9 = -12 + 11
-4x - 4 - 9 = -1
-4x - 13 = -1
-4x - 13 + 13 = -1 + 13
-4x = 12
-4x/-4 = 12/-4
x = -3
check:
-4(-3 + 1) -9 = -1
-4(-2) -9 = -1
8 -9 = -1
-1 = -1
