Image result for what is combination
A combination is a mathematical technique that determines the number of possible arrangements in a collection of items where the order of the selection does not matter.
Therefore, the number of possible groups or combination of three men can be formed from 10
= ![^{10} C_{3}](https://tex.z-dn.net/?f=%5E%7B10%7D%20C_%7B3%7D)
= 10!/ 3!7!
= 10(9)(8)/3(2)
= 5 × 3 × 8
= 120
The number of possible groups or combination of three men can be formed from 10 is 120.

You need to solve for x. This is how you do it:
![9 + 2x = 25](https://tex.z-dn.net/?f=9%20%2B%202x%20%3D%2025)
subtract 9 to both sides
![2x = 25 - 9](https://tex.z-dn.net/?f=2x%20%3D%2025%20-%209)
subtract 25 and 9
![x = 16/2](https://tex.z-dn.net/?f=x%20%3D%2016%2F2)
divide 2 to both sides
