Use the Gauss-Jordan method to solve the system of equations.
4x - 6y = 54
20x - 30y = 270
----------------
Subtract 5 times the 1st Eq. from the 2nd to get:
4x - 6y = 54
0 + 0 = 0
---------------
Solve the 1st equation for x:
6y = 4x-54
4x = 6y + 54
x = (3/2)y + (27)/2
-----------------------
The answer is "c".
