-3z-21+22=32z-52-17
Combine 15z and -18z to get -3z.
-3z+1=32z-52-17
Add -21 and 22 to get 1.
-3z+1=32z-69
Subtract 17 from -52 to get -69.
-3z+1-32z=-69
Subtract 32z from both sides.
-35z+1=-69
Combine -3z and -32z to get -35z.
-35z=-69-1
Subtract 1 from both sides.
-35z=-70
Subtract 1 from -69 to get -70.
z=\frac{-70}{-35}
Divide both sides by -35.
z=2
Divide -70 by -35 to get 2.
