your question is not clear,but as I understand this,I had solved
it is better to upload questions in such cases,or mention proper brackets,so that one can easily understand
 \frac{x + 1}{2}  +  \frac{y - 1}{3}  = 9 \\ take \: lcm \\  \frac{3(x + 1) + 2(y - 1)}{6}  = 9 \\ 3x + 3 + 2y - 2 = 54 \\ 3x + 2y = 54 - 3 + 2 \\ 3x + 2y = 53 \:  \:  \:  \:  \: eq1 \\  \frac{x - 1}{3}  + y + 2 = 8 \\  \frac{x - 1 + 3y + 6}{3}  = 8 \\ x + 3y + 5 = 24 \\ x + 3y = 24 - 5 \\ x + 3y =1 9 \:  \:  \:  \:  \:  \: eq2 \\ multiply \: eq2 \: by \: 3 \: and \: subtract \: both \: eq1 \: and \: 2 \\ 3x + 2y = 53 \\  - 3x - 9y =  - 57 \\  - 7y =  - 4 \\ y =  \frac{4}{7}  \\ x + 3( \frac{4}{7} ) =1 9 \\ x = 19 -  \frac{12}{7}  \\ x =  \frac{133 - 12}{7}  \\ x =  \frac{121}{7}
