You can put this solution on YOUR website! Solve the systems by substitution.
1st: 5x - 2y = -5
2nd: y - 5x = 3
-----------
Solve the 2nd for y to get:
3rd: y=5x+3
-------------
Substitute into the 1st to solve for "x", as follows:
5x-2(5x+3)=-5
5x-10x-6=-5
-5x=1
x=-1/5
-----------
Substitute into 3rd to solve for y, as follows:
y=5(-1/5)+3
y=-1+3
y=2
----------
Solution: x=-1/5 ; y=2
