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


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

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

Remove parenthesis around (3x)
3ln + lnx = ln * 3x

Reorder the terms for easier multiplication:
3ln + lnx = 3ln * x

Multiply ln * x
3ln + lnx = 3lnx

Solving
3ln + lnx = 3lnx

Solving for variable 'l'.

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

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

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

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

Factor out the Greatest Common Factor (GCF), 'ln'.
ln(3 + -2x) = 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 '(3 + -2x)' equal to zero and attempt to solve: Simplifying 3 + -2x = 0 Solving 3 + -2x = 0 Move all terms containing l to the left, all other terms to the right. Add '-3' to each side of the equation. 3 + -3 + -2x = 0 + -3 Combine like terms: 3 + -3 = 0 0 + -2x = 0 + -3 -2x = 0 + -3 Combine like terms: 0 + -3 = -3 -2x = -3 Add '2x' to each side of the equation. -2x + 2x = -3 + 2x Combine like terms: -2x + 2x = 0 0 = -3 + 2x Simplifying 0 = -3 + 2x 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.
