Hey friend,

Here is the answer you are searching for,

\frac{1}{x + 2} +  \frac{1}{x + 3}  =  \frac{2}{x + 9} \\  lcm \: of \: denominators \:  \\  = (x + 2)(x + 3) \\  =  > \frac{1}{x + 2}  +  \frac{1}{x + 3}  =  \frac{2}{x + 9} \\  =  >     \frac{(x + 3) + (x + 2)}{(x + 2)(x + 3)}  = \frac{2}{x + 9} \\  =  >  \frac{2x + 5}{ {x}^{2} + 2x + 3x + 6 }  = \frac{2}{x + 9} \\  =  > (2x + 5)(x + 9)  \ \\  = 2({ {x}^{2} + 5x + 6 }  ) \\  =  >  {2x}^{2}  + 5x + 18x \:  + 45  \\  =  {2x}^{2}  + 10x + 12 \\  =  > 23x + 45 = 10x + 12 \\  =  > 23x - 10x =  - 45 + 12 \\  =  > 13x =  - 33 \\  =  > x =  \frac{ - 33}{13}

HOPE IT HELPS YOU.
