(“{“ will replace the surd in this case) Given that 5{7 - {x / {7 - {x = 8 + {y where x and y are positive integers and {y is a surd in its simplest form, find the values of x and y (sorry I appreciate that this is hard to read)?

It's too difficult to read. You should make sure to use brackets to make it completely clear what it is you're trying to write, even if you don't need brackets it can be helpful. E.g. is it (sqrt(x) / sqrt(7)) - sqrt(x) Or is it sqrt(x) / ((sqrt(7) - sqrt(x)) Or maybe sqrt(x) / sqrt(7 - x) What I'm seeing though, is one equation with two unknowns, which isn't solvable. Are you missing some more information?
