Question 811483
x/2 - y/4 = -4 
x + y = -2 
The answer is (-6, 4), how do I get to this answer. 
-------
Multiply thru the top equation by 4 to get:
2x - y = -16
x  + y = -2
-------
Add and solve for "x":
3x = -18
x = -6
------
Solve for "y":
x + y = -2
-6 + y = -2
y = 4
---------------------
Solution: (-6,4)
