40=30-2x+2
Use the distributive property to multiply -2 by x-1.
40=32-2x
Add 30 and 2 to get 32.
32-2x=40
Swap sides so that all variable terms are on the left hand side.
-2x=40-32
Subtract 32 from both sides.
-2x=8
Subtract 32 from 40 to get 8.
x=\frac{8}{-2}
Divide both sides by -2.
x=-4
Divide 8 by -2 to get -4.
