Solve the equation $dfrac7x^2 - x + 4sqrt3x^2 - 1 + sqrtx^2 - x - xsqrtx^2 + 1 = 22$ over the reals.

WolframAlpha
tells me that there aren't any real solutions. I am thinking of a solution involving inequalities. (Obviously, that is not always the correct approach.)

  What do you mean with "a solution involving inequalities"? And why do you expect to be able to find (real) solutions, when WA tells you there aren't any?
