-x+4y = 8

2x-3y = -16

x= -17.6

y= -2.4

Is this right?

**drwls**, Monday, February 15, 2010 at 6:32pmNo, it is not right. How did you get that?

Convert the first equation (by doubling both sides) to:

-2x + 8y = 16

Put it above

2x - 3y = -16

and add both sides.

You get 5y = 0

It is pretty clear what y must be.
