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


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

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

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

Solving
5ln + lnx = -3ln + 3lnx

Solving for variable 'l'.

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

Add '3ln' to each side of the equation.
5ln + 3ln + lnx = -3ln + 3ln + 3lnx

Combine like terms: 5ln + 3ln = 8ln
8ln + lnx = -3ln + 3ln + 3lnx

Combine like terms: -3ln + 3ln = 0
8ln + lnx = 0 + 3lnx
8ln + lnx = 3lnx

Add '-3lnx' to each side of the equation.
8ln + lnx + -3lnx = 3lnx + -3lnx

Combine like terms: lnx + -3lnx = -2lnx
8ln + -2lnx = 3lnx + -3lnx

Combine like terms: 3lnx + -3lnx = 0
8ln + -2lnx = 0

Factor out the Greatest Common Factor (GCF), '2ln'.
2ln(4 + -1x) = 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 + -1x)' equal to zero and attempt to solve: Simplifying 4 + -1x = 0 Solving 4 + -1x = 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 + -1x = 0 + -4 Combine like terms: 4 + -4 = 0 0 + -1x = 0 + -4 -1x = 0 + -4 Combine like terms: 0 + -4 = -4 -1x = -4 Add 'x' to each side of the equation. -1x + x = -4 + x Combine like terms: -1x + x = 0 0 = -4 + x Simplifying 0 = -4 + 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.
