Answer: R = Y
Step-by-step explanation: 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:
