 \frac{2(2x - 1)}{(x  +  3)}  -  \frac{3(x + 3)}{(2x - 1))}  = 5 \\  \\  =  >  \frac{2 {(2x - 1)}^{2} - 3 {(x + 3)}^{2}  }{(x + 3)(2x - 1)}  = 5 \\  \\  =  >  \frac{2(4 {x}^{2} - 4x + 1) - 3( {x}^{2} + 6x + 9)  }{2 {x}^{2} - x + 6x - 3 }  = 5 \\  \\  =  > 8 {x}^{2}  - 8x + 2 - 3 {x}^{2}  - 18x - 27 = 10 {x}^{2}  + 25x  - 15 \\  \\  =  > 10 {x}^{2}  - 5 {x}^{2}  + 25x + 26x - 15 + 25 = 0 \\  \\  =  > 5 {x}^{2}  + 51x + 10 = 0 \\  \\  =  > 5 {x}^{2}  + 50x + x + 10 = 0 \\  \\  =  > 5x(x + 10) + 1(x + 10) = 0 \\  \\  =  > (5x + 1)(x + 10) = 0

Required values of x : -1/5 and -10
