I'm going to assume that this is your problem: If r = 5z and 15z = 3y, then r = ? r = 5z Multiply both sides of this equation by 3: 3r = 15z Now, we know that 3r = 15z and that 15z = 3y By the transitive property of equality, we can conclude that 3r = 3y Dividing both sides by 3 yields this: r = y If I have misinterpreted your problem, please reply with the exact wording that appears in your text.

Tell that to your teacher :!:
