Question:

 \frac{1}{x + 1}  +  \frac{1}{x + 2}  =  \frac{2}{x + 10}  \\

Answer:

Taking LCM by cross multiplying denominators.

  \implies\frac{1}{x + 1}  +  \frac{1}{x + 2}  =  \frac{2}{x + 10}  \\  \\  \implies \:  \frac{1(x + 2) + 1(x + 1)}{(x + 1)(x + 2)}   =  \frac{2}{x + 10}  \\  \\  \implies \:  \frac{x + 2 + x + 1}{x(x + 2) + 1(x + 2)}  =  \frac{2}{x + 10}  \\  \\  \implies \:  \frac{2x + 3}{ {x}^{2}  + 2x + x + 2}  =  \frac{2}{x + 10}  \\  \\  \implies \:  \frac{2x + 3}{ {x}^{2}  + 3x + 2}  =  \frac{2}{x + 10}  \\ \\ Again\: cross\: multiplying \\ \\  \implies \:  {(2x + 3)(x + 10)}  = 2( {x}^{2}  + 3x + 2) \\  \\   \small\implies \: 2x(x + 10) + 3(x + 10) = 2 {x}^{2}  + 6x + 4 \\  \\   \small \implies \: 2 {x}^{2}  + 20x +  3 x + 30 = 2 {x}^{2}  + 6x + 4 \\  \\  \implies \: 2 {x}^{2}  + 23x + 30 = 2 {x}^{2}  + 6x + 4 \\  \\  \implies \:  \cancel{2 {x}^{2} } + 23x + 30 =  \cancel{2 {x}^{2} } + 6x + 4 \\  \\  \implies \: 23x - 6x = 4 - 30 \\  \\  \implies \: 17x =  - 26 \\  \\  \implies \: x =  -  \frac{26}{17}

Hope it helps you
