answer is C

Step-by-step explanation:

let's consider the equation 1 and 2

2 - 1

(5x+ 5y+ 6z=5) - (4x+3y+6z=3)

5x+5y+6z- 4x- 3y - 6z = 5- 3

x+2y = 2

keep this equation aside

now consider equation 1 and 3

1 -3

4x+3y+6z - 6x- 3y - 6z = 3-3

-2x = 0

x= 0

x+2y =2

so 0+2y=2

y=1

consider any of the 3 equations

substitute x and y with 0 and 1 respectively

finally z= 0

so the correct combination is C
