At first,
- 7 = 9 + x
By subtracting 9 from both sides, we get
-7-9=9+x-9

By substituting the value of x in -3x + 5 , we get
-3x + 5
-3×(-16)+5
48+5

l=11.25 (total of both lengths, you divide that by 2 for one side.)
Step-by-step explanation:
l*w=20 ft
l=w+2 1/2 ft
w+2 1/2 *w= 20
-2 1/2
2w=17 1/2
divide by 2
w=8.75 l= 11.25
8.75+2.5 = 11.25
