Question

After you add both sides by 9. How can you solve for 5z in this equation?

5z– 3 = 12

Divide both sides by positive 5

Multiply both sides by positive 5

Multiply both sides by positive 3

Divide both sides by positive 3

Answer 1

The correct answer is A. Divide both sides by positive 5

Explanation:

Let's solve the equation for finding z and the necessary steps to do it:

5z - 3 = 12

5z = 12 + 3 (Adding 3 at the right side and subtracting 3 at the left side)

5z = 15 (Adding 12 plus 3 at the right side)

5z/5 = 15/5 (Dividing by positive 5 at both sides)

z = 3

The correct answer is A. Divide both sides by positive 5
