10x + 10y - 2z is the solution.

Step-by-step explanation:

We have to subtract the sum of 9x - 5y + 4z and 6x+2y+3z from the sum of 10x -3y+4z and 3x+6y-5z.

(10x - 3y + 4z) + ( 3x + 6y - 5z) - (9x - 5y + 4z) + ( 6x + 2y + 3z)

10x + 3x - 9x + 6x = 10x [x terms]

-3y +6y + 5y + 2y = 10y [y terms]

4z - 5z - 4z +3z = -2z [z terms]

10x + 10y - 2z is your answer
