x+2=4-3x-6
Use the distributive property to multiply -3 by x+2.
x+2=-2-3x
Subtract 6 from 4 to get -2.
x+2+3x=-2
Add 3x to both sides.
4x+2=-2
Combine x and 3x to get 4x.
4x=-2-2
Subtract 2 from both sides.
4x=-4
Subtract 2 from -2 to get -4.
x=\frac{-4}{4}
Divide both sides by 4.
x=-1
Divide -4 by 4 to get -1.
