Question

X/3x-y-z =y/3y-z-x=z/3z-x-y and x+y+z=#0 ratio 1 show

Answer 1

x / ( 3 x - y - z ) = y / ( 3 y - z - x ) = z / ( 3 z - x - y )

Each ratio is equal to :

( 3 x - y - z + 3 y - z - x + 3 z - x - y ) / ( x + y + z )

⇒ ( 3 x + 3 y + 3 z - 2 x - 2 z - 2 y ) / ( x + y + z )

⇒ ( x + y + z )/ ( x + y + z )

⇒ 1

Hence proved.
