Solution for lnx+ln(x-4)=ln(5x) equation:


Simplifying
lnx + ln(x + -4) = ln(5x)

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

Reorder the terms:
-4ln + lnx + lnx = ln(5x)

Combine like terms: lnx + lnx = 2lnx
-4ln + 2lnx = ln(5x)

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

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

Multiply ln * x
-4ln + 2lnx = 5lnx

Solving
-4ln + 2lnx = 5lnx

Solving for variable 'l'.

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

Add '-5lnx' to each side of the equation.
-4ln + 2lnx + -5lnx = 5lnx + -5lnx

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

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

Factor out the Greatest Common Factor (GCF), '-1ln'.
-1ln(4 + 3x) = 0

Ignore the factor -1.

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 '(4 + 3x)' equal to zero and attempt to solve: Simplifying 4 + 3x = 0 Solving 4 + 3x = 0 Move all terms containing l to the left, all other terms to the right. Add '-4' to each side of the equation. 4 + -4 + 3x = 0 + -4 Combine like terms: 4 + -4 = 0 0 + 3x = 0 + -4 3x = 0 + -4 Combine like terms: 0 + -4 = -4 3x = -4 Add '-3x' to each side of the equation. 3x + -3x = -4 + -3x Combine like terms: 3x + -3x = 0 0 = -4 + -3x Simplifying 0 = -4 + -3x 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.
