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
