2*x-47 = 3*(1/x) // - 3*(1/x)
2*x-(3*(1/x))-47 = 0
2*x-3*x^-1-47 = 0
2*x^1-3*x^-1-47*x^0 = 0
(2*x^2-47*x^1-3*x^0)/(x^1) = 0 // * x^2
x^1*(2*x^2-47*x^1-3*x^0) = 0
x^1
2*x^2-47*x-3 = 0
2*x^2-47*x-3 = 0
DELTA = (-47)^2-(-3*2*4)
DELTA = 2233
DELTA > 0
x = (2233^(1/2)+47)/(2*2) or x = (47-2233^(1/2))/(2*2)
x = (2233^(1/2)+47)/4 or x = (47-2233^(1/2))/4
x in { (47-2233^(1/2))/4, (2233^(1/2)+47)/4}
x in { (47-2233^(1/2))/4, (2233^(1/2)+47)/4 }
