Triangle Perimeter

import java.io.*;
/**
 * Problem: The third side of the triangle is 8 less than twice the sum of
 * the two other sides and the first side is 5 more than the thrice the
 * second side. If the perimeter is given, how long are its sides?
 * Input: float perimeter
 * Output: float sides
 * perimeter = 3 * second_side + 5 + second_side + 2 * (3 * second_side + 5) - 8
 * perimeter = 10 * second_side + 7
 * first_side = (3 * second_side) + 5
 * second_side = (perimeter - 7) / 10
 * third_side = 2 * (first_side + second_side) - 8
 * third_side = 2 * (3 * second_side + 5 * second_side) - 8
