2. The perimeter of a rectangular garden is 72 feet. If the width is 8 feet less than the length, write a system of
equations involving the length and width, L and W, I already solved this I just need help with equation

width -w

length l= 2*w+5

perimeter P=2w+2l, 52=2w+2l

system of equations:

52=2w+2l  > 26 =w+l  (1)

l= 2*w+5    (2)

substitute  value of l from second equation into the 1st

26=w+2w+5

26=3w+5

21=3w

w=7

l=2w+5,  l=2*7+5, l=19

system

52=2w+2l

l= 2*w+5  

length 19 ft, width 7 ft

the least common denominatore of 7 and 2 is 9

step-by-step explanation:

7+2=9

a is the right answer
