Solution for ln(x-3)-ln(x-2)=ln(x+5) equation:


Simplifying
ln(x + -3) + -1ln(x + -2) = ln(x + 5)

Reorder the terms:
ln(-3 + x) + -1ln(x + -2) = ln(x + 5)
(-3 * ln + x * ln) + -1ln(x + -2) = ln(x + 5)
(-3ln + lnx) + -1ln(x + -2) = ln(x + 5)

Reorder the terms:
-3ln + lnx + -1ln(-2 + x) = ln(x + 5)
-3ln + lnx + (-2 * -1ln + x * -1ln) = ln(x + 5)
-3ln + lnx + (2ln + -1lnx) = ln(x + 5)

Reorder the terms:
-3ln + 2ln + lnx + -1lnx = ln(x + 5)

Combine like terms: -3ln + 2ln = -1ln
-1ln + lnx + -1lnx = ln(x + 5)

Combine like terms: lnx + -1lnx = 0
-1ln + 0 = ln(x + 5)
-1ln = ln(x + 5)

Reorder the terms:
-1ln = ln(5 + x)
-1ln = (5 * ln + x * ln)
-1ln = (5ln + lnx)

Solving
-1ln = 5ln + lnx

Solving for variable 'l'.

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

Add '-5ln' to each side of the equation.
-1ln + -5ln = 5ln + -5ln + lnx

Combine like terms: -1ln + -5ln = -6ln
-6ln = 5ln + -5ln + lnx

Combine like terms: 5ln + -5ln = 0
-6ln = 0 + lnx
-6ln = lnx

Add '-1lnx' to each side of the equation.
-6ln + -1lnx = lnx + -1lnx

Combine like terms: lnx + -1lnx = 0
-6ln + -1lnx = 0

Factor out the Greatest Common Factor (GCF), '-1ln'.
-1ln(6 + x) = 0

Ignore the factor -1.

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 '(6 + x)' equal to zero and attempt to solve: Simplifying 6 + x = 0 Solving 6 + x = 0 Move all terms containing l to the left, all other terms to the right. Add '-6' to each side of the equation. 6 + -6 + x = 0 + -6 Combine like terms: 6 + -6 = 0 0 + x = 0 + -6 x = 0 + -6 Combine like terms: 0 + -6 = -6 x = -6 Add '-1x' to each side of the equation. x + -1x = -6 + -1x Combine like terms: x + -1x = 0 0 = -6 + -1x Simplifying 0 = -6 + -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.
