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).
