# Math Help - Line Segments equation

1. ## Line Segments equation

How would I go about doing this one:

Find XY if WX = 1/3(XY)

No big deal here:

$WX = x + 2$, $XY = 5x + 2$

since $WX = \frac 13 XY$, we have:

$x + 2 = \frac 13 (5x + 2)$

now solve for $x$, and plug that value into the formula for $XY$ to find its length
