Question

Find x:y:z from the equations : (Ratio and proportion)

$4x + y - 3z = 0 \: 2x - y - z = 0$
​

Answer 1

Step-by-step explanation:

4x+y-3z=0----->>1

2x-y-z=0------>>2

1+2

6x-4z=0

6x=4z

x=2/3z

4(2/3z)+y-3z=0

8z/3+y-3z=0

8z-9z/3+y=0

-z/3+y=0

y=z/3

2z/3:z/3:z

2/3:1/3:z

please mark my answer as brainliest it's very needed for me
