You can put this solution on YOUR website! 2x-3y=-6
3x+4y=12
----------------
Multiply thru 1st by 3
Multiply thru 2nd by 2
----------------
6x - 9y = -18
6x + 8y = 24
----------------
Subtract 1st from 2nd and solve for "y":
17y = 42
y = 42/17
-------------
Substitute for "y" and solve for "x":
3x + 4(42/17) = 12
3x + (168/17) = 204/17
3x = 36/17
x = 12/17
