Answer 1

$\huge{\underline{\underline{\tt{\orange{ANSWER:-}}}}}$

$\huge\rightarrow$ 2a - 3b - [3a- {4b + 2(5a - b)}]

$\huge\rightarrow$ 2a - 3b - [3a - {4b + 10a - 2b}]

$\huge\rightarrow$ 2a - 3b - [3a - {2b + 10a}]

$\huge\rightarrow$ 2a - 3b - [3a - 2b - 10a]

$\huge\rightarrow$ 2a - 3b - [-7a - 2b]

$\huge\rightarrow$ 2a - 3b + 7a + 2b

$\huge\rightarrow$ 4a + 4b

The answer is 4a + 4b
