 the answer i keep getting is x=12 and y=-15 however, x=6 and y=-7.5 seems to work. just want to make sure there isnt another answer.

You have an equation relating TWO variables.....there are infinite answers to this......if you need ONE discreet answer , you will need another equation relating the two variables (x,y)....

 

If you pick ANY value for 'x'  there will be another value for 'y' that will work.....infinite answers !
