well what are you trying to do...solve it....simplify it?
Simplified is X+Y=-4
Lets assume you want to solve for either x or y.
1) If you want to solve for x, we have to take y=0. When we fill this into the equation, we get that:
-4X+0=16
=> -4X=16
=> X=-4
2) If you want to solve for Y, you have to take x=0. When we fill this into the equation we get that:
0+Y=16
=>Y=16
