Answer 2

Answer:

here,

x+y+z = 10

Step-by-step explanation:

Here,

x-y = 1. ...(i)

2y = 4. ...(ii)

2y+z = 9 ...(iii)

x+y = 5. ...(iv)

from eq (i) and (iv), we get

x - y = 1

x + y = 5

_______

2x = 6

x = 3

put the value of x in eq (i)

x-y = 1

or, y = 2

put the value of y in eq (iii), we get

2y + z = 9

or,. z = 5

therefore,

x + y + z = 3 + 2+ 5

= 10
