The perimeter of a rectangle is the sum of its sides, which are two widths and two lengths:

$p=w+w+l+l$

Since the length is twice the width, we have $l=2w$ , and the formula for the perimeter becomes

$p=w+w+2w+2w=6w$

So, we have

$6w=120 \iff w=\dfrac{120}{6}=20$

x=y+2
2y=x-1
substitute x=y+2 into 2y=x-1

2y=x-1
2y=y+2 -1
2y - y = 1
y = 1

x=y+2
x=1+2
x=3

answer
x = 3 and y = 1
