If order mattered, then there would be 6*5*4*3 = 30*12 = 360 different ways to form the committee. However, no single member outranks the other. Each member has equal ranking. So order does not matter.
Since order does not matter, we must consider all of the ways to arrange a single group of 4 people. That is 4! = 4*3*2*1 = 24 ways. We overcount by a factor of 24 when order doesn't matter which is why we divide the previous result (360) by 24 to get 360/24 = 15
Answer: 15
Note: you can use the combination formula n C r = (n!)/(r!*(n-r)!) with n = 6 and r = 4 to get the same answer

Answer:
![f=-\frac{6g}{5}](https://tex.z-dn.net/?f=f%3D-%5Cfrac%7B6g%7D%7B5%7D)
Step-by-step explanation:
Given: ![6f + 9g = 3g +f](https://tex.z-dn.net/?f=6f%20%2B%209g%20%3D%203g%20%2Bf)
To solve for the value
we need to isolate it on one side of the equal sign. Let's move the
on the right side to the left side by subtracting it from both sides. We then get:
![5f + 9g = 3g](https://tex.z-dn.net/?f=5f%20%2B%209g%20%3D%203g)
Subtract
from both sides of the equal sign to isolate the ![5f.](https://tex.z-dn.net/?f=5f.)
![5f= -6g](https://tex.z-dn.net/?f=5f%3D%20-6g)
To solve for
we need to divide both sides by
since it is being multiplied by ![f.](https://tex.z-dn.net/?f=f.)
![\frac{5f}{5} =\frac{-6g}{5}\\f=-\frac{6g}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B5f%7D%7B5%7D%20%3D%5Cfrac%7B-6g%7D%7B5%7D%5C%5Cf%3D-%5Cfrac%7B6g%7D%7B5%7D)
