You cannot eliminate x and end up with two different equations.
5x+3y=9.. B
2x-4=40…A
Solve A for x.
2x – 4 = 40
2x = 40 + 4
2x = 44
x = 44/2
x = 22
The only thing I can think of doing is to plug 22 into B.
5(22) + 2y = 9
110 + 2y = 9…This leads to an answer for y.
No two NEW EQUATIONS is possible.
2y = 9 – 110
2y = -101
y = -101/2
