Answer:

There are two ways of solving the given Question

Method-1

Solve all the three equations using any of the following ways:

Elimination Method

Substitution Method

Cross Multiplication Method

After solving the equations you will get the values of x, y, and z

Then apply the formula to evaluate the Average.

Method-2

Given equations are:

x+y=6 _____(1)

y+z=7 _____(2)

z+x=9 _______(3)

Adding all the three equations, we get

2(x+y+z)=22

⇒x+y+z=11

To find the Average,

Apply the formula and get the required answer.

⇒Average=x+y+z3

⇒Average=113=3.6

Answer:

24

Step-by-step explanation:

As there average is 5 so,

x-4=5

y-3=5

z-2=5

So now we will take numbers to RHS to get values of x, y and z .

so we get

x = 4+5 = 9

y = 3+5 = 8

z = 2+5 = 7

As the question is to add x+y+z ,so we will put values instead of x, y, z

So we get it like this:

x+y+z = 9+8+7 = 24
