Question

The length of the first side of a triangle is 3 more than twice the second side, and three half of the third side. Find the lengths of the sides if the perimeter of the triangle is 31.

Answer 1

x = 15

y = 6

z = 10

Explanation:

Okay, let's set up the equation(s).

x = 3 + 2y

x = 3/2z

x + y + z = 31

With some algebra that God knows how came through my mind, I got this:

x = 15

y = 6

z = 10
