4z-8-5+4=4-4z+8
Use the distributive property to multiply 4 by z-2.
4z-13+4=4-4z+8
Subtract 5 from -8 to get -13.
4z-9=4-4z+8
Add -13 and 4 to get -9.
4z-9=12-4z
Add 4 and 8 to get 12.
4z-9+4z=12
Add 4z to both sides.
8z-9=12
Combine 4z and 4z to get 8z.
8z=12+9
Add 9 to both sides.
8z=21
Add 12 and 9 to get 21.
z=\frac{21}{8}
Divide both sides by 8.
