Answer 2

$\huge \boxed{ \boxed{ \boxed{x \: = \: 6}}}$

proof:-

$\huge \underline{ \underline{given}}$

$\huge \red{ \boxed{b \: - \: 7 \: = - 1}}$

$\huge \: b \: \: = \: \: - 1 \: + \: 7$

$\huge \blue{ \fbox{ \fbox{b \: \: = \: \: \: 6}}}$

$\huge { \green{ \underline{ \underline{note \ : - }}}}$

$\huge \blue{ \sf \bigstar{if \: there \: is \: ( + )}}$

$\huge \blue{ \sf {in \: rhs \: then \: it \: is}}$

$\huge\blue {\sf{( - ) \: in \: lhs}}$

$\huge \green{ - - - ---- - - - }$

$\huge \blue{ \sf \bigstar{if \: there \: is \: ( - )}}$

$\huge \blue{ \sf {in \: rhs \: then \: it \: is}}$

$\huge\blue {\sf{( + ) \: in \: lhs}}$

$\huge \green{ - - - - --- - - - }$
