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
