5z+40-7=z+8+13
Use the distributive property to multiply 5 by z+8.
5z+33=z+8+13
Subtract 7 from 40 to get 33.
5z+33=z+21
Add 8 and 13 to get 21.
5z+33-z=21
Subtract z from both sides.
4z+33=21
Combine 5z and -z to get 4z.
4z=21-33
Subtract 33 from both sides.
4z=-12
Subtract 33 from 21 to get -12.
z=\frac{-12}{4}
Divide both sides by 4.
z=-3
Divide -12 by 4 to get -3.
