Answer:

z = 7

Step-by-step explanation:

Simplifying:

25(z + -2) = 125

Reorder the terms:

25(-2 + z) = 125

(-2 * 25 + z * 25) = 125

(-50 + 25z) = 125

Solving:

-50 + 25z = 125

Move all terms containing z to the left, all other terms to the right.

Add '50' to each side of the equation.

-50 + 50 + 25z = 125 + 50

Combine like terms: -50 + 50 = 0

0 + 25z = 125 + 50

25z = 125 + 50

Combine like terms: 125 + 50 = 175

25z = 175

Divide each side by '25'.

z = 7
