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]
