**Jake1214**, Friday, November 28, 2008 at 8:44amTranslate these info into equations:

y=3/5x

x=5/3y

y+140=2x

Now you can use substitution method to solve for x easily.

**Reiny**, Friday, November 28, 2008 at 10:55amalternate solution:

let the height of pant X be 5x

let the height of plant Y be 3x

5x/(3x+140) = 1/2

10x = 3x+140

x= 20

then X = 5x = 100

Y = 3x = 60

check : if 140 is added to 60, Y = 200

then X:Y = 1:2
