Answer 1

Step-by-step explanation:

Given :-

x+y+z = 10

x+z = 7

x+y = 8

To find :-

Find x-y-z ?

Solution :-

Given that

x+y+z = 10 ----------(1)

x+z = 7 --------------(2)

x+y = 8 --------------(3)

On substituting x+y value in (1) then

=> 8+z = 10

=> z = 10-8

=> z = 2

On substituting the value of z in (2) then

=> x+2 = 7

=> x = 7-2

=> x = 5

On substituting the value of x in (3) then

=> 5+y = 8

=> y = 8-5

=> y = 3

Therefore, x = 5 , y = 3 and z = 2

Now,

The value of x-y-z

=> 5-3-2

=> 5-5

=> 0

Answer:-

The value of x-y-z for the given problem is 0

Check:-

If x = 5 , y = 3 and z = 2 then

x+y+z = 5+3+2 = 10

x+z = 5+2 = 7

x+y = 5+3 = 8
