Answer: R = Y

Step-by-step explanation: I'm going to assume that this is your problem:

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:
