PLS DO IT FAST IT IS IMPORTANT​

Answer 1

Step-by-step explanation:

we have,

$\rm 11x-[8y-\{ 11x-(7z-3y) + 5y-(3x-2y-z) \} ]$

$\rm \Longrightarrow 11x-[8y-\{ 11x-7z+3y + 5y-3x+2y+z \} ]$

$\rm \Longrightarrow 11x-[8y-\{ 11x-3x-7z+z+3y+5y+2y \} ]$

$\rm \Longrightarrow 11x-[8y-\{ 8x-6z+10y \} ]$

$\rm \Longrightarrow 11x-[8y- 8x+6z-10y ]$

$\rm \Longrightarrow 11x-[-2y- 8x+6z ]$

$\rm \Longrightarrow 11x+2y+8x-6z$

$\rm \Longrightarrow 11x+8x+2y-6z$

$\rm \Longrightarrow 19x+2y-6z$
