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
