Answer:

-4x + 6y - 2z

Step-by-step explanation:

(3x +2y- 4z) + (4y-5x+8z ) + (-2x-6z.)

= 3x + 2y - 4z + 4y - 5x + 8z - 2x - 6z

= 3x - 5x - 2x + 2y + 4y - 4z + 8z - 6z

= -4x + 6y - 2z

Answer:

( 3x + 2y - 4z ) + ( 4y - 5x + 8z ) + ( -2x - 6z )

= 3x - 2x - 5x + 2y + 4y + 8z - 6z - 4z

= -4x + 6y -2z
