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


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

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

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

Multiply -1 * 5
-3ln + lnx + -5ln = -1ln(x)

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

Combine like terms: -3ln + -5ln = -8ln
-8ln + lnx = -1ln(x)

Multiply ln * x
-8ln + lnx = -1lnx

Solving
-8ln + lnx = -1lnx

Solving for variable 'l'.

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

Add 'lnx' to each side of the equation.
-8ln + lnx + lnx = -1lnx + lnx

Combine like terms: lnx + lnx = 2lnx
-8ln + 2lnx = -1lnx + lnx

Combine like terms: -1lnx + lnx = 0
-8ln + 2lnx = 0

Factor out the Greatest Common Factor (GCF), '2ln'.
2ln(-4 + x) = 0

Ignore the factor 2.

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 '(-4 + x)' equal to zero and attempt to solve: Simplifying -4 + x = 0 Solving -4 + x = 0 Move all terms containing l to the left, all other terms to the right. Add '4' to each side of the equation. -4 + 4 + x = 0 + 4 Combine like terms: -4 + 4 = 0 0 + x = 0 + 4 x = 0 + 4 Combine like terms: 0 + 4 = 4 x = 4 Add '-1x' to each side of the equation. x + -1x = 4 + -1x Combine like terms: x + -1x = 0 0 = 4 + -1x Simplifying 0 = 4 + -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.
