Solution for 1/3ln(x-1)=1 equation: 


D( x )

x-1 <= 0

x-1 <= 0

x-1 <= 0

x-1 <= 0 // + 1

x <= 1

x in (1:+oo)

(1/3)*ln(x-1) = 1 // - 1

(1/3)*ln(x-1)-1 = 0

1/3*ln(x-1)-1 = 0 // + 1

1/3*ln(x-1) = 1 // : 1/3

ln(x-1) = 1/1/3

ln(x-1) = 3

ln(x-1) = ln(e^3)

x-1 = e^3

x-e^3-1 = 0 // + e^3+1

x = e^3+1

x = e^3+1
