Try subtracting the first equation from the second equation and see what you get. Can you proceed from here?
Are you able to proceed?
so 2x-2x?
yes
so it would give you..6-8.5=-2.5???

thank you but how do you work out a value for x?? or cant you??
i'm suppose to help you through, not to do everything for you
you should be able to divide that

now you got y so you can put into either of the equations to find x
