How do I set up this word problem??

**Jai**, Sunday, October 23, 2011 at 10:24amfirst represent the unknown using variable:

let x = time required so that they will have the same number of rows.

recall that rate = quantity/time, or quantity = rate*time

in this problem, quantity refers to number of rows knitted.

to set-up the equation, what we only know is that at this particular time, x, their quantities must be equal. thus we add for both number of rows they initially knitted and their rate times the required time, or:

quantity (of you) = quantity (of friend)

10 + 8x = 19 + 5x

hope this helps~ :)
