Question 153220
9x-2y=-47
8x+48=y 
------------
Rearrange to use elimination:
9x - 2y = -47
8x - y  = -48
-----------------
Now the objective is to have the same number of x's or y's in both equations.
So, multiply the 2nd equation by 2 and rewrite the system.
-----------------
9x - 2y = -47
16x -2y  = -96
==============
Subtract the 1st equation from the 2nd to get:
7x = -49
x = -7
-----------------
Substitute into 8x+48=y to solve for "y":
y = 8*-7 + 48
y = -56 + 48
y = -7
-------------
Final solution: (-7,-7)
===============
