**PsyDAG**, Monday, September 26, 2011 at 12:14pmLet x = # dimes and y = # of nickels.

x + y = 26

y = 26-x

10x + 5y = 210

Substitute 26-x for y in second equation and solve for x. Insert that value into the first equation and solve for y. Check by inserting both values into the second equation.
