-2x-2=3\left(x+1\right)
Use the distributive property to multiply -2 by x+1.
-2x-2=3x+3
Use the distributive property to multiply 3 by x+1.
-2x-2-3x=3
Subtract 3x from both sides.
-5x-2=3
Combine -2x and -3x to get -5x.
-5x=3+2
Add 2 to both sides.
-5x=5
Add 3 and 2 to get 5.
x=\frac{5}{-5}
Divide both sides by -5.
x=-1
Divide 5 by -5 to get -1.
