Answer 2

$\ \: \: \: \: \: \: let \: the \: number \: be \: = x$

$\: \: \: \: \:\: \: \: \:second \: number \: = 7$

$\: \: \: \: sum \: of \: two \: numbers \: = 15$

$\: \: \: \: \underline{according \: to \: question}$

$\: \: \: \: \: \: \: \: \: \: \: \:\: \: x + 7 = 15$

$\: \: \: \: \: \: \: \: \: \: \: \: \: x \: = 15 - 7$

$\: \: \: \: \: \: \: \ \: \: \ \: \: \: x \: = 8$

$\pink{hence \: the \: second \: number \: is \: 8}$
