    so you know distance formula will be involved? and you want one distance to be 3 times the other, right?

    ok we have this line |dw:1402446909617:dw| we want the distance from E to F be equal 3 times the distance from D to F You should have an equation here I just called F (x,y) since we don't know it yet and we are looking for that value x

    I'm asking you to translate "the distance from E to F" is "3 times the distance from D to F"

    replace the word is with an equal sign replace the distance from E to F with the distance formula and the points entered from E and F and do the same thing from D to F (which is on the other side of equation because it is on the other side of the is)
