Solution for ln(x-1)+ln^3=lnx equation:


Simplifying
ln(x + -1) + ln3 = lnx

Reorder the terms:
ln(-1 + x) + ln3 = lnx
(-1 * ln + x * ln) + ln3 = lnx
(-1ln + lnx) + ln3 = lnx

Add '-1lnx' to each side of the equation.
-1ln + lnx + -1lnx + ln3 = lnx + -1lnx

Combine like terms: lnx + -1lnx = 0
-1ln + 0 + ln3 = lnx + -1lnx
-1ln + ln3 = lnx + -1lnx

Combine like terms: lnx + -1lnx = 0
-1ln + ln3 = 0

Solving
-1ln + ln3 = 0
