Answer:
2x - 11y + 16z
Step-by-step explanation:
( 5x + 4y + 5z ) + ( 5x - 6y + 7z )
= 5x + 4y + 5z + 5x - 6y + 7z
= 5x + 5x + 4y - 6y + 5z + 7z
= 10x - 2y + 12z
Now, 10x - 2y + 12z - ( 8x + 9y - 4z )
= 10x - 2y + 12z - 8x - 9y + 4z
= 10x- 8x - 2y - 9y + 12z + 4z
= 2x - 11y + 16z
HOPE THIS WILL HELP YOU.
