x = 2/2
x = 1

Answer 2

Answer :

$\: given \: equation \: = \: 3x + 5 = x + 7 \\ \\ firstly \: collect \: the \: like \: terms \: \\ \\ = > \: 3x - x = - 5 + 7 \\ \\ now \: add \: the \: numbers \: \\ \\ = > \: 2x = 2 \\ \\ = > \: x = \frac{2}{2} \\ \\ = > \: x = 1 \\ \\ \\ verification \: - - \\ \\ = > \: put \: the \: value \: of \: x \: in \: the \: given \: equation \: \\ \\ = > \: 3(1) + 5 = (1) + 7 \\ \\ = > \: 3 + 5 = 1 + 7 \\ \\ = > \: 8 = 8 \\ \\ \: l.h.s \: = \: r.h.s \\ \\ hence \: proven$
