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


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

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

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

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

Combine like terms: 1ln + ln = 2ln
2ln + lnx = -1ln + ln + 3lnx

Combine like terms: -1ln + ln = 0
2ln + lnx = 0 + 3lnx
2ln + lnx = 3lnx

Add '-3lnx' to each side of the equation.
2ln + lnx + -3lnx = 3lnx + -3lnx

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

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

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