Answer 2

Question:

check weather X=2 is solution of 2X+7=13

Answer:

$substituting \: x = 2 \: in \: the \: given \: equation \\ \\ 2x \: + 7 \\ = \: 2 \times 2 + 7 \\ = 4 + 7 \\ = 11 \\ which \: is \: not \: equal \: to \: 13 \\ \\ hence \: x \: = 2 \: is \: not \: a \: solution \\ \: of \: the \: given \: equation \:$
