You can put this solution on YOUR website!
 2x + 3y =  2
 4x + 2y = -3

To eliminate the x-terms multiply the top equation through by -2

-4x - 6y = -4
 4x + 2y = -3
-------------
     -4y = -7
       y = %28-7%29%2F%28-4%29
       y = 7%2F4

----------------------------

 2x + 3y =  2
 4x + 2y = -3


To eliminate the y-terms multiply the top equation through by -2
and multiply the bottom equation through by 3

-4x - 6y =  -4
12x + 6y =  -9
---------------
 8x      = -13
       x = -13%2F8
