Solution for 2x4/5z=420 equation: 


x in (-oo:+oo)

((2*x^4)/5)*z = 420 // - 420

((2*x^4)/5)*z-420 = 0

2/5*x^4*z = 420 // : 2/5*z

x^4 = 1050*z^-1

x^4 = 1050*z^-1 // ^ 1/4

abs(x) = 1050^(1/4)*z^(-1/4)

x = 1050^(1/4)*z^(-1/4) or x = -(1050^(1/4)*z^(-1/4))

x in { 1050^(1/4)*z^(-1/4), -(1050^(1/4)*z^(-1/4)) }
