Hello Dear ✔️✔️↙️↙️

$solution: \\ \\ LHS \\ RHS \\ \\ \implies x + (y +z ) \\ \\ \implies (x + y ) + z \\ \\ \implies \: \frac{-3}{ \: \: 5} + ( \frac{ - 7}{10} - \frac{8}{15} ) \\ \\ \implies( \frac{ - 3}{5} - \frac{7}{10} ) \: - \frac{8}{15} \\ \\ \implies \frac{ - 3}{ 5} \: ( \frac{ - 21 - 16}{15} ) \\ \\ \implies \: (\frac{ - 6 - 7}{10} ) \: - \frac{8}{15} \\ \\ \implies \: \frac{ - 3}{5} - \frac{37}{30} \\ \\ \implies \: \frac{ - 3}{10} - \frac{8}{15} \\ \\ \implies \: \frac{ - 18 - 37}{30} \\ \\ \implies \: \frac{ - 39 - 16}{30} \\ \\ \implies \: \frac{ - 55}{30} \\ \\ Hence, \: \: \: x + (y + z) = (x + y) + z \\ \\ = \frac{ - 55}{30}$
