Answer:
(-1/2,-5/2)
Step-by-step explanation:
x-y = 2
x+y = -3
---------------
Through Elimination, we can just add the system of equations. The y cancels out and gives us the single equation for x:
2x = -1
x = -1/2
Substitute -1/2 for x in either equation and you get:
(-1/2) + y = -3 Solve for y
y = -5/2
