Solve this system:

-5y + 8x = -18
 5y + 2x =   58

Note that if you merely add these 2 equations together, you will have eliminated the variable y.  Please do this now.  8x+2x=58-18

Solve for x.
Then subst. your value for x into either of the original equations to find the value of y.

Write your final result (solution) in the form (x,y).
