Reasoning The diagram shows a rug laid on a wooden floor. Its width is 2 m less than the width of the room.
a Write an equation to represent the width of
the room (y).
b Write an equation to represent the area of
the rug, which is 3 m?.
< Use these two equations to find the value of x
and hence the width of the room (y).
