Answer 2

$\sf{\red{\boxed{\bold{Solution}}}}$

⠀⠀⠀⠀

$\sf:\implies \: {\bold{ a - ( a - b ) - b - ( 2b - a ) }}$

⠀⠀⠀⠀

$\sf:\implies \: {\bold{ a - a + b - b - 2b + a }}$

⠀⠀⠀

$\sf:\implies \: {\bold{ a - a + a +b - b - 2b }}$

⠀⠀⠀⠀

$\sf:\implies \: {\bold{ a + b - b - 2b}}$

⠀⠀⠀⠀

$\sf:\implies \: {\bold{ a - 2b}}$
