Step-by-step explanation:
4x - 3y + 2z, 2x + 5y - 3z, 6x-9z, 8y + 3z-2x + 4
3x + y - z = 3 , 2x – 8y + z = -5 , x – 2y + 9z = 8 . 4. x + 2y + 3z = 6 ; 2x + 4y + z = 7 ; 3x + 2y + 9z = 14 . 5. 4x + y + 3z = 11 ; 3x + 4y + 2z = 11 ...

Answer:
(x+3y−4z)+(2x+y−z)+(−2x+3y−z)−(2x−4y+3z)
=(x+2x+3y+y−4z−z)+(−2x+3y−z)−(2z−4y+3z)
=(3x+4y−5z)+(−2x+3y−z)−(2x−4y+3z)
=(x+7y−6z)−(2x−4y+3z)
=x−2x+7y+4y−6z−3z
=−x+11y−9z
∴ Ans is (−x+11y−9z)
