Find the root(s) of this algebraic equation?

x³ + 6 = 7 ³√(7 x - 6)

It's an exercise I have invented

I'd like you to test it

thank you in advance

Update:

@rotchm

(x³ + 6)/7

and

³√(7 x - 6)

are one the inverse function of the other

thus the real solutions are the solutions of

(x³ + 6)/7 = x

which are the one that you have found
