Answer 2

Answer:

25x-10y-4z ( pl check answer)

Step-by-step explanation:

11x-[ 8y- {11x-(8z-3y)+5y-(3x+4z)}]

=11x-[ 8y- {11x-8z+3y} +5y-3x-4z}] solving small bracket()

=11x-[8y-11x+8z-3y+5y-3x-4z] solving bracket { }

=11x- [-14x+13y-3y+8z-4z] solving bracket [ ]

=11x-[-14x+10y+8z]

=11x+14x-10y-4z

=25x-10y-4z
