I'd start by drawing them.

Excuse my ignorance but what d0es the horizontal line on top of CD  and  others mean?

sshayer · Answer

as L is the mid point of CD
so CL=LD
find x

sshayer · Answer

CD=2CL

quickstudent · Answer

The line means line segment

agent0smith · Answer

Oh I see. The way they wrote it originally seemed like they meant they were functions, as in y =

It's just segments of a line. |dw:1469737067853:dw| Set them equal since L is the midpoint.

quickstudent · Answer

But I don't understand how to do that. I'm kind of confused

get all the terms with x on one side, and all the other terms on th eother side

@quickstudent 
So far you have made no attempt to contribute to the solution.

You now have the explanation of what is needed , and it is a simple equation with x in it

solve the eqation as described above for the value of x

THEN I will help you with the final step....
