I'm going to need a little more than this. Or you to describe the question better.

Assuming that the equation is

138+5=17x-19=L?

Each side is 143 cm long. (I am also assuming measurements.)

So take 143+19, and you get 160. Divide that by 7, and you get about 22.8571. It doesn't seem like the right answer...
