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

Check your question again.
