\large\mathsf{Given \ two \ equations \ :-}

\textbf{23h - 29k = 98}

\mathsf{And}

\textbf{29h - 23k = 110}

\mathsf{First} \textbf{add} \mathsf{these \ equations \ -}

\mathsf{23h - 29k + 29h - 23k \ = \ 98 + 110}

\mathsf{52h - 52k \ = \ 208}

\mathsf{52(h - k) \ = \ 208}

\textbf{h - k \ = \ 4} _______(1)

\mathsf{Second} \textbf{subtract} \mathsf{these \ equations \ -}

\mathsf{(23h - 29k) - (29h - 23k) \ = \ 98 - 110}

\mathsf{23h - 29k - 29h + 23k = - 12}

\mathsf{- 6h - 6k \ = \ - 12}

\mathsf{- 6(h + k) \ = \ - 12}

\textbf{h + k = 2} _______(2)

\mathsf{Add \ (1) \ and \ (2)}

\mathsf{h - k + h + k \ = \ 4 + 2}

\mathsf{2h \ = \ 6}

\large\mathsf\red{\boxed{h \ = \ 3}}

\mathsf{Put \ this \ in \ (2)}

\mathsf{3 + k \ = \ 2}

\large\mathsf\red{\boxed{k \ = \ - 1}}
