Have you tried expanding the left side of the first equation? –  mb7744 Jun 16 at 23:34

Note that since $(25-y)(x+8)=200+25x-8y-xy$ we get $xy=0$. –  André Nicolas Jun 16 at 23:40

1 Answer 1

Hint: You can rewrite the second equation as $y=\frac 18(25x-323)$, substitute that into the first and you will have a quadratic equation. It will give you two values for $x$, which you can plug into the second to find $y$.
