Solution for ln(4x+4)=ln(3x-1) equation:


Simplifying
ln(4x + 4) = ln(3x + -1)

Reorder the terms:
ln(4 + 4x) = ln(3x + -1)
(4 * ln + 4x * ln) = ln(3x + -1)
(4ln + 4lnx) = ln(3x + -1)

Reorder the terms:
4ln + 4lnx = ln(-1 + 3x)
4ln + 4lnx = (-1 * ln + 3x * ln)
4ln + 4lnx = (-1ln + 3lnx)

Solving
4ln + 4lnx = -1ln + 3lnx

Solving for variable 'l'.

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

Add 'ln' to each side of the equation.
4ln + ln + 4lnx = -1ln + ln + 3lnx

Combine like terms: 4ln + ln = 5ln
5ln + 4lnx = -1ln + ln + 3lnx

Combine like terms: -1ln + ln = 0
5ln + 4lnx = 0 + 3lnx
5ln + 4lnx = 3lnx

Add '-3lnx' to each side of the equation.
5ln + 4lnx + -3lnx = 3lnx + -3lnx

Combine like terms: 4lnx + -3lnx = 1lnx
5ln + 1lnx = 3lnx + -3lnx

Combine like terms: 3lnx + -3lnx = 0
5ln + 1lnx = 0

Factor out the Greatest Common Factor (GCF), 'ln'.
ln(5 + x) = 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 '(5 + x)' equal to zero and attempt to solve: Simplifying 5 + x = 0 Solving 5 + x = 0 Move all terms containing l to the left, all other terms to the right. Add '-5' to each side of the equation. 5 + -5 + x = 0 + -5 Combine like terms: 5 + -5 = 0 0 + x = 0 + -5 x = 0 + -5 Combine like terms: 0 + -5 = -5 x = -5 Add '-1x' to each side of the equation. x + -1x = -5 + -1x Combine like terms: x + -1x = 0 0 = -5 + -1x Simplifying 0 = -5 + -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.
