x=\dfrac{-12}{13}

Step-by-step explanation:

We have,

x^{2} +12x-\dfrac{20}{3}x-5=x^{2}  +8x+\dfrac{12}{2}x+3

To find, the value of x = ?

x^{2} +12x-\dfrac{20}{3}x-5=x^{2}+8x+\dfrac{12}{2}x+3

12x-\dfrac{20}{3}x-5=8x+\dfrac{12}{2}x+3

12x-\dfrac{20}{3}x-5=8x+6x+3

12x-\dfrac{20}{3}x=14x+3+5

-2x-\dfrac{20}{3}x=8

\dfrac{-6x-20x}{3}=8

-26x=24

x=\dfrac{-24}{26} =\dfrac{-12}{13}

Hence, x=\dfrac{-12}{13}.
