Problema Solution

A number, twice that number, and one-third of that numberare added. The result is 20. What is the original number?

Answer provided by our tutors

Let the number = x

twice that number = 2 * x

one-third of that number = 1/3 * x

 

Now x+ 2x + x/3 = 20

3x + (x/3) = 20

9x + x = 60

10x = 60

x = 6 answer
