Solution for 0=-ln(x-1) equation:


Simplifying
0 = -1ln(x + -1)

Reorder the terms:
0 = -1ln(-1 + x)
0 = (-1 * -1ln + x * -1ln)
0 = (1ln + -1lnx)

Solving
0 = 1ln + -1lnx

Solving for variable 'l'.

Move all terms containing l to the left, all other terms to the right.

Add '-1ln' to each side of the equation.
0 + -1ln = 1ln + -1ln + -1lnx
Remove the zero:
-1ln = 1ln + -1ln + -1lnx

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

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

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

Factor out the Greatest Common Factor (GCF), 'ln'.
ln(-1 + x) = 0

Subproblem 1

Set the factor 'ln' equal to zero and attempt to solve: Simplifying ln = 0 Solving ln = 0 Move all terms containing l to the left, all other terms to the right. Simplifying ln = 0 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.

Subproblem 2

Set the factor '(-1 + x)' equal to zero and attempt to solve: Simplifying -1 + x = 0 Solving -1 + x = 0 Move all terms containing l to the left, all other terms to the right. Add '1' to each side of the equation. -1 + 1 + x = 0 + 1 Combine like terms: -1 + 1 = 0 0 + x = 0 + 1 x = 0 + 1 Combine like terms: 0 + 1 = 1 x = 1 Add '-1x' to each side of the equation. x + -1x = 1 + -1x Combine like terms: x + -1x = 0 0 = 1 + -1x Simplifying 0 = 1 + -1x The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined. The solution to this equation could not be determined.
