Question 500499: The lengths (in inches) of two sides of a regular pentagon are represented by the expressions 5x-27 and 2x-6. Find the length of a side of the pentagon.
I'm not sure how to set this up, this section of geometry is confusing me.

The only geometry is that the sides are equal.
5x-27 = 2x-6
3x = 21
x = 7
side = 8
