Answer:

The value of x is -9 or 7.    

Explanation:

\frac{1}{x-3}-\frac{1}{x+5}=\frac{1}{6}\\or,\frac{x+5-x+3}{(x-3)(x+5)}=\frac{1}{6}\\or,\frac{8}{x^{2}+5x-3x-15}=\frac{1}{6}\\or,48=x^{2}+2x-15\\or,x^{2}+2x-63=0\\or,x^{2}+9x-7x-63=0\\or,x(x+9)-7(x+9)=0\\or,(x+9)(x-7)=0\\

either,x+9=0                or,x-7=0

x=-9                 ⇒x=7

∴The value of x is -9 or 7.
