If it's not what You are looking for type in the equation solver your own equation and let us solve it.
x in (-oo:+oo)
Y = (-4/5)*x^22 // - (-4/5)*x^22
Y-((-4/5)*x^22) = 0
Y+(4/5)*x^22 = 0
4/5*x^22 = -Y // : 4/5
x^22 = -5/4*Y
x^22 = -5/4*Y // ^ 1/22
abs(x) = (-5/4)^(1/22)*Y^(1/22)
x = (-5/4)^(1/22)*Y^(1/22) or x = -((-5/4)^(1/22)*Y^(1/22))
x in { (-5/4)^(1/22)*Y^(1/22), -((-5/4)^(1/22)*Y^(1/22)) }
