A 15 feet piece of string is cut into two pieces so that the longer piece is 3 feet longer than twice the shorter piece. If the shorter piece is x feet long, find the lengths of both pieces.

If the shorter piece is x, the longer piece is 20 - x

We also are given
15 - x = 2x + 3

Add x to each side:
3x + 3 = 15

Using our equation calculator, we get a shorter piece of:
x = 4

The longer piece is:
15 - x
15 - 4
11
