Answer:

z = -1

Explanation:

-3z - (3z - 2) = 4(z + 3)

Expand -3z - (3z - 2): -6z + 2

Expand 4(z + 3): 4z + 12

-6z + 2 = 4z + 12

Subtract 2 from both sides

-6z + 2 - 2 = 4z + 12 - 2

Simplify

-6z = 4z + 10

Subtract 4z from both sides

-6z - 4z = 4z + 10 - 4z

Simplify

-10z = 10

Divide both sides by -10

-10z / -10 = 10 / -10

Simplify

z = -1
