$\implies \large {\sf{5 + 2(x - 1) = 5}}$

$\implies \large {\purple{\sf{7(x - 1) = 5}}}$

$\implies \large {\purple{\sf{7x - 7 = 5}}}$

$\implies \large {\purple{\sf{7x = 5 + 7}}}$

$\implies \large {\purple{\sf{7x = 12}}}$

$\implies \large {\purple{\sf{x = \frac{12}{7} }}}$

$\implies \large {\purple{\sf{x = \frac{12}{7} \: or \: 1 \frac{5}{7}. }}}$

$\implies \large {\red{\sf{By \: putting \: the \: value:—}}}$

$\implies \large {\purple{\sf{5 + 2( \frac{12}{7} - 1) = 5}}}$

$\implies \large {\purple{\sf{5 + 2( \frac{12 - 7}{7}) = 5 }}}$

$\implies \large {\purple{\sf{5 + 2( \frac{5}{7}) = 5 }}}$

$\implies \large {\purple{\sf{7( \frac{5}{7}) = 5 }}}$

$\implies \large {\purple{\sf{ \frac{35}{7} = 5 }}}$

$\implies \large {\purple{\sf{ \frac{ \cancel{35}}{ \cancel{7}} = 5}}}$

$\implies \large {\purple{\sf{ \frac{5}{1} = 5 }}}$

$\implies \large {\purple{\sf{ \frac{5 \times 1}{5} }}}$

$\implies \large {\purple{\sf{ \frac{5 \times 1}{5} = \frac{5}{5} }}}$

$\implies \large {\purple{\sf{ \frac{ \cancel{5}}{ \cancel{5}} = 1}}}$

$\implies \large {\red{\sf{So \: its \: answer \: is \: 1.}}}$
