Three times a number, less twice the number and 9 is 17. What is the number?
Harlamova29_29 [7]
I believe your answer is 8.

Three times a number less than twice the number and nine is seventeen can be written as: 3n - 2n + 9 = 17

Solve for n as follows:

3n - 2n = n 

n + 9 = 17

17 - 9 = 8

Hope this helps! :)
