Answer 2

$\bf \textcolor {blue}{ - 25 - 17 - 5(6 - 7) - 3( - 5) = } \\ \\ \bf \textcolor {blue}{ - 42 - 5( - 1) + 15 = } \\ \\ \bf \textcolor{blue}{ - 27 + 5 = } \\ \\ \boxed { - 22}$

$\bf \textcolor{red}{ - 15 + 19 - 6(8 - 7) - 2( - 3) = } \\ \\ \bf \textcolor{red}{4 - 6(1) + 6 = } \\ \\\bf \textcolor{red}{10 - 6 = } \\ \\ \boxed {4}$
