Well, using "X" is probably a bad idea.
Changing to "x" int eh middle of the problem is another bad idea.
Super Big Clue that will Change Your Life --- WRITE DOWN DEFINITIONS!!
L = Length
W = Width
L*W = Area
"area of a rectangle is 54 ft2"
L*W = 54
" length of the rectangle is 3 ft more than twice the width."
L = 3 + 2W
Substitute for L
(3+2W)*W = 54
2W^2 + 3W - 54 = 0
