Solution for lnx-ln(x+1)=ln(x-2) equation:


Simplifying
lnx + -1ln(x + 1) = ln(x + -2)

Reorder the terms:
lnx + -1ln(1 + x) = ln(x + -2)
lnx + (1 * -1ln + x * -1ln) = ln(x + -2)
lnx + (-1ln + -1lnx) = ln(x + -2)

Reorder the terms:
-1ln + lnx + -1lnx = ln(x + -2)

Combine like terms: lnx + -1lnx = 0
-1ln + 0 = ln(x + -2)
-1ln = ln(x + -2)

Reorder the terms:
-1ln = ln(-2 + x)
-1ln = (-2 * ln + x * ln)
-1ln = (-2ln + lnx)

Solving
-1ln = -2ln + lnx

Solving for variable 'l'.

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

Add '2ln' to each side of the equation.
-1ln + 2ln = -2ln + 2ln + lnx

Combine like terms: -1ln + 2ln = 1ln
1ln = -2ln + 2ln + lnx

Combine like terms: -2ln + 2ln = 0
1ln = 0 + lnx
1ln = lnx

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

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

Factor out the Greatest Common Factor (GCF), 'ln'.
ln(1 + -1x) = 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 + -1x)' equal to zero and attempt to solve: Simplifying 1 + -1x = 0 Solving 1 + -1x = 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 + -1x = 0 + -1 Combine like terms: 1 + -1 = 0 0 + -1x = 0 + -1 -1x = 0 + -1 Combine like terms: 0 + -1 = -1 -1x = -1 Add 'x' to each side of the equation. -1x + x = -1 + x Combine like terms: -1x + x = 0 0 = -1 + x Simplifying 0 = -1 + x 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.
