Solution for ln(2x)=ln(3x)+ln(4x+5) equation:


Simplifying
ln(2x) = ln(3x) + ln(4x + 5)

Remove parenthesis around (2x)
ln * 2x = ln(3x) + ln(4x + 5)

Reorder the terms for easier multiplication:
2ln * x = ln(3x) + ln(4x + 5)

Multiply ln * x
2lnx = ln(3x) + ln(4x + 5)

Remove parenthesis around (3x)
2lnx = ln * 3x + ln(4x + 5)

Reorder the terms for easier multiplication:
2lnx = 3ln * x + ln(4x + 5)

Multiply ln * x
2lnx = 3lnx + ln(4x + 5)

Reorder the terms:
2lnx = 3lnx + ln(5 + 4x)
2lnx = 3lnx + (5 * ln + 4x * ln)
2lnx = 3lnx + (5ln + 4lnx)

Reorder the terms:
2lnx = 5ln + 3lnx + 4lnx

Combine like terms: 3lnx + 4lnx = 7lnx
2lnx = 5ln + 7lnx

Solving
2lnx = 5ln + 7lnx

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.
-5ln + 2lnx = 5ln + -5ln + 7lnx

Combine like terms: 5ln + -5ln = 0
-5ln + 2lnx = 0 + 7lnx
-5ln + 2lnx = 7lnx

Add '-7lnx' to each side of the equation.
-5ln + 2lnx + -7lnx = 7lnx + -7lnx

Combine like terms: 2lnx + -7lnx = -5lnx
-5ln + -5lnx = 7lnx + -7lnx

Combine like terms: 7lnx + -7lnx = 0
-5ln + -5lnx = 0

Factor out the Greatest Common Factor (GCF), '-5ln'.
-5ln(1 + x) = 0

Ignore the factor -5.

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