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?

(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.

Finishing the problem from there should be easy.
