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
[tex] {x}^{2} - 7 = 6x[/tex]
After that bring 6X to the LHS of the equation
so that it will look like the general equation that is
[tex] {x}^{2} - 6x - 7 = 0[/tex]
Use the quadratic formula (or any other approach to find the values of x
You will arrive at
[tex]x = 7. - 1[/tex]
