Question

42 = -7 ( z-3)

whats z?

Answer 1

Answer and Step-by-step explanation:

We have to solve for z. That means everything that is next to z has to move to the other side of the equation.

First, divide -7 from both sides of the equation.

-6 = z - 3

Now add 3 to both sides of the equation.

-3 = z

z is equal to -3.
