Notice that the least common denominator is 9*2=18, therefore:


\begin{gathered} (x-3)/(9)+(x+7)/(2)=(2(x-3))/(9\cdot2)+(9(x+7))/(9\cdot2), \\ (x-3)/(9)+(x+7)/(2)=(2x-6)/(18)+(9x+63)/(18), \\ (x-3)/(9)+(x+7)/(2)=(2x-6+9x+63)/(18), \\ (x-3)/(9)+(x+7)/(2)=(11x+57)/(18)\text{.} \end{gathered}

Answer:


(x-3)/(9)+(x+7)/(2)=(11x+57)/(18)\text{.}
