Answer:

 \frac{5}{2x + 1}  +  \frac{6}{x + 1}  = 3 \\  \\  \\  \frac{5(x + 1) + 6(2x + 1)}{(2x + 1)(x + 1)}  = 3 \\  \\  \\  \\  \frac{5x + 5 + 12x + 6}{ {2}x^{2}  + 2x + x + 1}   = 3 \\  \\  \\  \\ 17x + 11 = 6 {x}^{2}  + 9x + 3 \\  \\  \\ 8x + 8 = 6 {x}^{2}  \\  \\ 4x + 4 = 3 {x}^{2}  \\  \\  \\ 3 {x}^{2}  - 4x - 4 = 0 \\  \\ 3 {x}^{2}  - 6x  + 2x - 4 = 0 \\  \\  \\ 3x(x - 2) + 2(x - 2) = 0 \\  \\  \\ (3x + 2)(x - 2) = 0 \\  \\ 3x + 2 = 0 \\  \\ x =  \frac{ - 2}{3}  \\  \\  \\  \\ x - 2 = 0 \\  \\ x = 2
