3x + 2y = 5
-3x - y = -12
A. 19/3, -7
B. (2,1)
C. (5,-5)

You can put this solution on YOUR website! The easiest way to solve this system is to add the equations
3x + 2y = 5
-3x - y = -12
---------------
y = -7
Now substitute that into the second one and get x...
-3x -(-7) = -12
-3x + 7 = -12
-3x = -19
x = 19/3
Choice A.
