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
