Name: John Paul Who is asking: Student Question: I solved the problem and I got the following values
for each variable. I don't see nothing wrong, but the teacher checked it as wrong. Could it be a checking mistake? Thank you for your attention. John Paul 

Hi John Paul, The way to verify is to substitute back your values for the variables
in the original equations: (b) RmTm=480 becomes 96*5 = 480; (c) Rm=2Rc becomes 96 = 2*40; (d) Tm+Tc=15 becomes 5 + 9 = 15.
