2z-2-5=3\left(3+z\right)+z
Use the distributive property to multiply 2 by z-1.
2z-7=3\left(3+z\right)+z
Subtract 5 from -2 to get -7.
2z-7=9+3z+z
Use the distributive property to multiply 3 by 3+z.
2z-7=9+4z
Combine 3z and z to get 4z.
2z-7-4z=9
Subtract 4z from both sides.
-2z-7=9
Combine 2z and -4z to get -2z.
-2z=9+7
Add 7 to both sides.
-2z=16
Add 9 and 7 to get 16.
z=\frac{16}{-2}
Divide both sides by -2.
z=-8
Divide 16 by -2 to get -8.
