Solution for ln(x/100)=-1 equation: 


D( x )

x/100 <= 0

x/100 <= 0

x/100 <= 0

1/100*x+0 <= 0 // - 0

1/100*x <= 0 // : 1/100

x <= 0/1/100

x <= 0

x in (0:+oo)

ln(x/100) = -1 // + 1

ln(x/100)+1 = 0

ln(x/100)+1 = 0 // - 1

ln(x/100) = -1

ln(x/100) = ln(e^-1)

x/100 = e^-1

x/100-e^-1 = 0

1/100*x-e^-1 = 0 // + e^-1

1/100*x = e^-1 // : 1/100

x = (e^-1)/1/100

x = 100*e^-1

x = 100*e^-1
