The answer is C that is X=7 and X=-1
multiple x through the given equation to get rid of a fraction. It will be
![{x}^{2} - 7 = 6x](/tpl/images/0602/6812/81fae.png)
After that bring 6X to the LHS of the equation
so that it will look like the general equation that is
![{x}^{2} - 6x - 7 = 0](/tpl/images/0602/6812/94cef.png)
Use the quadratic formula (or any other approach to find the values of x
You will arrive at
![x = 7. - 1](/tpl/images/0602/6812/80102.png)
