Multiply the first equation by 2 and look around for some magic.
thank. you.
4x=4/4=1. x=1

2y=11
And adding the two equations produces the same result as before?
Try to remember that there may be more than one way to proceed. Don't get all excited when you see a potential solution. Keep your eyes open for other ways to go about it.
oh. -3(1)+2y=-15
y=-4
