**Reiny**, Monday, October 26, 2009 at 10:14pmFirst thing I would do is get rid of my fractions by multiplying each term by the LCD

so multiply by 4

1/2x-1/4y=7/2

2x - y = 14

Take all terms except the y term to the right side

-y = -2x + 14

divide by -1

y = 2x - 14

repeat the same steps for your second equation and let me know what you got.
