Question 1122282: 2 LINEAR EQUATIONS IN 2 UNKNOWNS or SIMULTANEOUS LINEAR EQUATIONS IN 2 UKNOWNS
if twice the length of a rectangle is increased by three times the width, the sum is 48 feet. The perimeter is 40 feet what are the dimensions of the rectangle? Answer by greenestamps(13200) (Show Source):
(1) Twice the length of a rectangle increased by three times the width is 48 feet: 2w+3l = 48
(2) The perimeter is 40 feet: 2w+2l = 40
Either by looking at those equations, or by thinking logically about the given information, the difference between those two measurements is the width of the rectangle.
