Attached below is a step by step process of arriving at the answer.
X+3y=3
First add subtract the x
3y=-x+3
Then divide 3
Y=-1/3x+1
Ive never seen a question lie this before
Since the first figure is a square I guess it stand for x^2
then we have -2x + 3x = x ( the 2 stets of rectangles)
and finally -3 + 1 = - 2
So i am presuming its x^2 + x - 2
Option b
Im not sure though
