What you would do is you would keep subtracting (I recommend a calculator for this task) from both accounts until you get an equal amount for each. You would also have to record this down that way you know each time what you got. (And please do not put the calculator part). Really hope this helps!!!

stepan [7]
Length= y in.
Width= (y-6) in.
Perimeter = 2(L*W)
Perimeter=2L+2W
68in.=2(y)+2(y-6)
68=2y+2y-12
68=4y-12
68+12=4y
4y=80
y=20
Length= 20 inches, width =14 inches
