Y=2x-1 i think that would be your answer.
Lets say our problem is 12÷24 which ofc equals 2, well we could figure it out by thinking hmmmm what is 12 x __ that equals 24?
Answer:

Step-by-step explanation:

A = L * W
A = 99
L = 2W + 7
99 = W(2W + 7)
99 = 2W^2 + 7W
-2W^2 - 7W + 99 = 0
(-2W + 11)(W + 9) = 0
-2W + 11 = 0
-2W = -11
W = -11/-2
W = 5.5
W + 9 = 0
W = -9 .....not this one because it is negative
so the width (W) = 5.5ft <====
L = 2W + 7 .....2(5.5) + 7 = 18 ft is the length (L) <==
