The formula for an average of three numbers is (x+y+z)/3.  So if V equals the average, then we find the formula
V = (x+y+z)/3
We are now looking for x.  We can divide each of the variables in the parentheses by 3, making the formula
V = x/3 + y/3 + z/3
So now bring the unwanted variables to the same side as V.
V - y/3 - z/3 = x/3
Now multiply both sides by 3 to find x.
3V - y - z = x

x = 3V - y - z

The remaining number, using the concept of average, is  [tex]3V-y-z[/tex]

It is given that

Average of three numbers = V

One number  = z

Another number = y

What is an average?

Average is the sum of observations divided by a number of observations.

Let us take the third number  x

From the question

[tex]\frac{x+y+z}{3} = V[/tex]

[tex]x+y+z = 3V\\\\x=3V-y-z[/tex]

Therefore, the remaining number is [tex]3V-y-z[/tex]
