Given:


(2)/(x-5)=(x-4)/(6)

Required:

To find the value of x.

Step-by-step explanation:

Consider the given equation,


(2)/(x-5)=(x-4)/(6)
\begin{gathered} (x-5)(x-4)=12 \\ x^2-5x-4x+20=12 \\ x^2-9x+20=12 \\ x^2-9x+8=0 \end{gathered}

Now, the value of x is


\begin{gathered} x=(-9\pm√(81-32))/(2) \\ =(-9\pm√(49))/(2) \\ =(-9\pm7)/(2) \end{gathered}
\begin{gathered} x=(-9+7)/(2) \\ =(-2)/(2) \\ =-1 \end{gathered}

OR


\begin{gathered} x=(-9-7)/(2) \\ =-(16)/(2) \\ =-8 \end{gathered}

Final Answer:

The values of x are


x=-1,-8
