to solve this problem you use elimination
-----------------------
5x - 2y = -15
3x + 3y = 12
----
To eliminate the x-terms:
Multiply the 1st equation by 3.
Multiply the 2nd equation by 2.
------------------------------------
15x - 6y = -45
6x + 6y = 24
---------------------
Add the two equations to get:
21x = -21
x = -1
---------------------------------
Substitute into 5x-2y=-15 to solve for "y":
5*-1-2y=-15
-5 -2y =-15
-2y = -10
y = 5
-----------------------
Solution: (-1,5)
