Linear equations help!

The perimeter of a rectangle is 30 ft. the length is 11ft longer than the width. let x be the length and y be the width. Write the system of two linear equations. don't solve

Define variables
l =length, w = width
Perimeter = 2(l = w)
EQUATION (1)
2(l - w) = 30
Length is 11 feet longer than the width
EQUATION (2)
l = w + 11

2W+2L=30=Perimeter

W-11=L
L+11=W

2(L+11)+2L=30
2L+22+2L=30
4L+22=30
4L=52
L=52/4
L=13
W=2
