You can put this solution on YOUR website! -2x-9y=-25
-4x-9y=-23
-------------------
subtract the 2nd equation from the 1st
and solve for "x":
2x = -2
x = -1
------------------
Substitute x = 1 into the 1st equation and solve for "y":
-2(1) - 9y = -25
-9y = -23
y = 23/9
----------------------
Solution: (-1 , 23/9)
