8-5z=20+5z
Combine -7z and 2z to get -5z.
8-5z-5z=20
Subtract 5z from both sides.
8-10z=20
Combine -5z and -5z to get -10z.
-10z=20-8
Subtract 8 from both sides.
-10z=12
Subtract 8 from 20 to get 12.
z=\frac{12}{-10}
Divide both sides by -10.
z=-\frac{6}{5}
Reduce the fraction \frac{12}{-10} to lowest terms by extracting and canceling out 2.
