Answer:

x + y = 0 ......eq. 1

y + z = 2 ......eq. 2

x + z = 4 ........eq. 3

Adding eq. 1 , eq. 2 & eq. 3

x + y + y + z + x + z = 0 + 2 + 4

2( x + y + z) = 6

° x + y + z = 6/2 = 3

therefore, the value of. x + y + z = 3

Answer:

z=3

Step-by-step explanation:

from eqn 2-----> y=2-z

from eqn 3 ----> x=4-z

put this x,y in eqn 1....

So,

2-z+4-z=0

6-2z=0

2z=6

so,

z=3

x=1

y= -1
