**drwls**, Sunday, April 5, 2009 at 8:27pmYour first two equations are not independent. One can be derived from the other. Ordinarily, this would imply that there are an infinite number of solutions.

However, your last equation tells you what x is. Did you derive that equation or was it provided? You can use x = -4 and either of the first two equations to compute y.

-32 - 5y = 20

5y = -52
