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


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

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

Remove parenthesis around (3x)
5ln + lnx = ln * 3x

Reorder the terms for easier multiplication:
5ln + lnx = 3ln * x

Multiply ln * x
5ln + lnx = 3lnx

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

Combine like terms: lnx + -3lnx = -2lnx
5ln + -2lnx = 3lnx + -3lnx

Combine like terms: 3lnx + -3lnx = 0
5ln + -2lnx = 0

Factor out the Greatest Common Factor (GCF), 'ln'.
ln(5 + -2x) = 0


Subproblem 1
Set the factor 'ln' equal to zero and attempt to solve:
