Question

12x + 2y = 112
What does x equal???
What does y equal???

Answer 1

12x+2y=112
6x+y=56
6x=56-y

x=(56-y)/6
y=(56-6x)

Answer 2

2y=-12x+112                12x=-2y+112
y=-6x+56                         x=-1/6y+28/3

To find the value of x or y, you must know what the other is. But the equation can be changed to y=-6x+56 or x=-1/6y +28/3
