Let w be the width of the deck. Then, using the total area, we get:
(9+2w)(18+2w)=400
4w²+54w-238=0
2w²+27w-119=0
(2w-7)(w+17)=0
w=-17 or 7/2
Using the positive value, we get a width of 3&1/2 ft. for the deck

Answer:
(14,3)
Step-by-step explanation:
2x + y = 19
x - y = 11
-2(x - y) = -2(11)
-2x + 2y = -22
-2x + 2y = -22 + 2x + y = 19
3y = -3
y = 3
-------------------------------------------------
x - y = 11
x - 3 = 11
x = 11 + 3
x = 14
