Answer 1

$let \: unknown \: numbers \: be \: x \: and \: y \: respectively. \\ therefore \: let \: x \: = \: y \: - 2\: \\ given \: that \: x \: + \: y \: = \: 29 \\ therefore \: \: y \: - \: 2 \: + \: y \: = \: 29 \\ 2y \: - \: 2 \: = \: 29 \\ 2y \: = \: 29 \: - \: 2 \\ 2y \: = \: 27 \\ y \: = \: \frac{27}{2 } \\ x \: = \: \frac{27}{2} \: - \: 2 \\ therefore \: x \: = \: \frac{27}{2} \: - \: \frac{4}{2} \\ x \: = \: \frac{23}{2} \\ hope \: this \: answer \: is \: helpful \\ please \: mark \: as \: the \: brainliest \: answer \\ please \: thank \: my \: math \: answers \\ have \: a \: great \: day \: ahead \\ answer \: by \: amrutha \: varshini$
