My questin is If r=5z then 15z=3y, then r=
I just can't seem to determine how to set this problem up. I tried subsutition but that doesn't work for me either? Thanks in advance
I assume you want to define r in terms of y.
If r = 5z, then 3r = 15z.
Therefore, 3r = 3y.
I'm sure you can take it from there. I hope this helps. Thanks for asking.
