Solution for ln(6x)-ln(x+1)=ln(4) equation:


Simplifying
ln(6x) + -1ln(x + 1) = ln(4)

Remove parenthesis around (6x)
ln * 6x + -1ln(x + 1) = ln(4)

Reorder the terms for easier multiplication:
6ln * x + -1ln(x + 1) = ln(4)

Multiply ln * x
6lnx + -1ln(x + 1) = ln(4)

Reorder the terms:
6lnx + -1ln(1 + x) = ln(4)
6lnx + (1 * -1ln + x * -1ln) = ln(4)
6lnx + (-1ln + -1lnx) = ln(4)

Reorder the terms:
-1ln + 6lnx + -1lnx = ln(4)

Combine like terms: 6lnx + -1lnx = 5lnx
-1ln + 5lnx = ln(4)

Reorder the terms for easier multiplication:
-1ln + 5lnx = 4ln

Solving
-1ln + 5lnx = 4ln

Solving for variable 'l'.

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

Add '-4ln' to each side of the equation.
-1ln + -4ln + 5lnx = 4ln + -4ln

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

Combine like terms: 4ln + -4ln = 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.
