Solve by the elimination method.
6x-9y=13.5
7y-3x= -8
-----------------
Rearrange:
6x - 9y=13.5
-3x+7y = -8
--------------------
Multiply thru the 2nd equation by 2 to get:
6x - 9y = 13.5
-6x + 14y = -16
===================
Add to get:
5y = -2.5
y = -5
----------------------
Substitute into 7y-3x= -8 to solve for "x":
7*-5 - 3x = -8
-35 - 3x = -8
3x = -27
x = -9
-----------------
