x in (-oo:+oo)
((1/2)*x^55*x^265*y)/(10^3) = 7.29*y // - 7.29*y
((1/2)*x^55*x^265*y)/(10^3)-(7.29*y) = 0
((1/2)*x^55*x^265*y)/(10^3)-7.29*y = 0
1/2000*x^320*y = -(-7.29*y) // : 1/2000*y
x^320 = 14580
x^320 = 14580 // ^ 1/320
abs(x) = 14580^(1/320)
x = 14580^(1/320) or x = -14580^(1/320)
x in { 14580^(1/320), -14580^(1/320) }
