Answer: z = 0 | Equation is not solvable

Step-by-step explanation:

We have 3 = 7 - 2(3z + 2)

When we distribute the 2, we get: -6z - 4 + 7 = 3

Combine like terms: -6z + 3 = 3

Subtract the left hand side 3 from the right hand side 3: -6z = 0

We can not divide by zero thus the equation is not solvable.
