$\bold\green{Question:}\small\tt{The \: sum \: of \: two \: rational \: numbers \: is \: -1/36. \: If \: one \: of \: them \: is \: 7/18, \: find \: the \: other.}$

$\bold\green{Solution : } \\ \\ \tt{Given,} \\ \tt{ \: sum \: of \: two \: numbers \: is \: \: \frac{ - 1}{36}. } \\ \tt{one \: of \: them \: is \: \frac{7}{18} .} \\ \\ \tt{ \: we \: have \: to \: find \: the \: other \: number} \\ \\ \tt{let \: the \: other \: number \: be \: x} \\ \\ \tt{According \: \: to \: \: question,} \\ \tt{ \frac{ 7}{18} + x = \frac{ - 1}{36} } \\ \\ \tt{\implies \: x = \frac{ - 1}{36 } - \frac{7}{18} }\\ \\ \tt{\implies \: x = \frac{ - 1 - 14}{36} }\\ \\ \tt{\implies \: x = \frac{ - 15}{36} }\\ \\ \tt{\implies \: x = \frac{ - 5}{12} } \\ \\ \rm{\therefore \: x = \frac{ - 5}{12} } \\ \\ \huge\boxed{ \: the \: other \: number \: is \: \frac{ - 5}{12} }$
