Rearrange the second equation so that you have an 'x=...' or a 'y=...'

Then put that into the first equation.

You can use the first suggestion or you can make X the subject for both then make the 2 equations equal.

Using second equation,x=12/y


Now put this into the first equation and you'll have a solution for y.
