**PsyDAG**, Thursday, February 16, 2012 at 10:36pmThey cannot be solved. Add 2x to both sides of the second equation in the pair to see this.

You have a typo in the last equation. If it is -y, then they are unsolvable. If positive y, then add the two equations to get 8x = 4 or x = 4/8 = 1/2

It would help if you proofread your questions before you posted them.
