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
