Solution for 2e^1/x=42 equation: 


D( x )

x = 0

x = 0

x = 0

x in (-oo:0) U (0:+oo)

(2*e^1)/x = 42 // - 42

(2*e^1)/x-42 = 0

(2*e)/x-42 = 0

2*e*x^-1 = 42 // : 2*e

x^-1 = 21*e^-1

-1 < 0

1/(x^1) = 21*e^-1 // * x^1

1 = 21*e^-1*x^1 // : 21*e^-1

1/(21*e^-1) = x^1

x = 1/(21*e^-1)

x = 1/(21*e^-1)
