The length of DE is the length of CE minus the length of CD.
Substitute the values from the problem statement for CD, DE, and CE in the equation:
DE=CE=CD
Solve for x. x is the length of CD.

I would write it as CD=n, where n is the value you calculated. Some instructors prefer you to put a line over the top of CD to indicate that this is a line segment.
