Solve using elimination
7x + 3y = -4
6x + 7y = 32
====================
multiply thru 1st by 7
multiply thru 2nd by 3
-------
49x + 21y = -12
18x + 21y = 96
--------
Subtract 2nd from 1st and solve for "x":
31x = -108
x = -108/31
--------------------
Substitute into 6x + 7y = 32 to solve for "y":
6(108/31) + 7y = 32
7y = 32 - 6(-108/31)
7y = 52.9032
y = 1640/217
