Question

The length of a rectangle is 2 meters less than 2 times the width. The perimeter is 20 meters. Find the width.

Answer 1

The equation you'd make would be (2x-2)+(2x-2)+x+x=20 because the length is 2 m less than the width (x). To simplify, it'd be 6x-4=20 because you combine like terms. You then move the -4 over to the 20 to make it 6x=24. The final answer is 4 meters.
