**PsyDAG**, Monday, April 12, 2010 at 1:52pmSubstitute 25-5y for x in the first equation and solve for y. Put that value in the second equation to find x. Check by putting both values into the first equation.

It is not clear what the second problem is or what you are doing with the second problem.
