according to the question,

now,

is the required answer .

Answer:[tex]\huge\mathfrak\purple{Answer}[/tex]

= x – 3y + 2z + (-4x) + 9y – 11z – (3x – 4y – 7z)

= x – 3y + 2z – 4x + 9y – 11z – 3x + 4y + 7z

= x – 4x – 3x + 2z – 11z + 7z + 9y + 4y

= -3x – 3x + 2z – 4z + 13y

= -6x – 2z + 13y

Step-by-step explanation:Hope this helps you.
