x-7%28x%2B2%29=-4x%2B4 Start with the given equation.


x-7x-14=-4x%2B4 Distribute.


-6x-14=-4x%2B4 Combine like terms on the left side.


-6x=-4x%2B4%2B14 Add 14 to both sides.


-6x%2B4x=4%2B14 Add 4x to both sides.


-2x=4%2B14 Combine like terms on the left side.


-2x=18 Combine like terms on the right side.


x=%2818%29%2F%28-2%29 Divide both sides by -2 to isolate x.


x=-9 Reduce.
