To start with, put both equations in the form Ax+By=C and simplify.

8x + 64 = 8y
8x - 8y = -64
x - y = -8

-4x + 4y = 32
x - y = -8

The two equations are equivalent; any solution to one equation is a solution to the other. There is no unique (x,y) solution.

If you want a solution in (x,y) form, then solve the equation for y in terms of x and write the solution parametrically:

x - y = -8
y = x+8

Solution: (x,x+8) where x is any number
