. While this might look confusing, it is easier than you think: divide both sides by (x-70) for 
. From here, try factoring the top: there is a -90 difference between -70 and -160 and luckily -70 times -90 equals 6300. So, your equation should look like 
. You can eliminate (x-70) from the top and bottom, so you should get l=x-90 . Since there is no way to find x, x-90 is your length.
