Question 612910: The width of a rectangle is 3 m less than twice its length. (By m I think it means meter, not a variable.) If the ratio of the length to the width is 7/5, find the dimensions of the rectangle.

Length/Width = 7/5
L/(2L-3) = 7/5
5L = 7(2L-3)
5L = 7(2L-3)
5L = 14L-21
5L-14L = -21
-9L = -21
L = -21/(-9)
L = 7/3
W = 2L - 3
W = 2(7/3) - 3
W = 14/3 - 3
W = 14/3 - 9/3
W = 5/3
So the width is 5/3 m and the length is 7/3 m
