SOLUTION

$\frac{x + 1}{2} + \frac{y - 1}{ 3} = 9 \\ take \: lcm \\ \frac{3(x + 1) + 2(y - 1)}{6} = 9 \\ \frac{3x + 3 + 2y - 2}{6} = 9 \\ 3x + 2y + 1 = 54 \\ 3x + 2y = 53.......eq(1) \\ \\ \\ \frac{x - 1}{3} + \frac{y + 1}{2} = 8 \\ 2(x - 1) + 3(y + 1) = 48 \\ 2x - 2 + 3y + 3 = 48 \\ 2x + 3y + 1 = 48 \\ 2x + 3y = 47........eq(2) \\ \\ 3x + 2y = 53 (multiply \: by \: 2)\\ 2x + 3y = 47(multiply \: by \: 3) \\ \\ 6x + 4y = 106\\ 6x + 9y = 141 \\ subtract \: both \: the \: equation \\ \\ - 5y = - 35 \\( y = 7) \\ \\ put \: this \: in \: any \: of \: the \: equation \\ 2x + 3(7) = 47 \\ 2x + 21 = 47 \\ 2x = 26 \\ (x = 13)$
