Solution for ln(x-23)-ln(5-x)=ln(4x) equation:


Simplifying
ln(x + -23) + -1ln(5 + -1x) = ln(4x)

Reorder the terms:
ln(-23 + x) + -1ln(5 + -1x) = ln(4x)
(-23 * ln + x * ln) + -1ln(5 + -1x) = ln(4x)
(-23ln + lnx) + -1ln(5 + -1x) = ln(4x)
-23ln + lnx + (5 * -1ln + -1x * -1ln) = ln(4x)
-23ln + lnx + (-5ln + 1lnx) = ln(4x)

Reorder the terms:
-23ln + -5ln + lnx + 1lnx = ln(4x)

Combine like terms: -23ln + -5ln = -28ln
-28ln + lnx + 1lnx = ln(4x)

Combine like terms: lnx + 1lnx = 2lnx
-28ln + 2lnx = ln(4x)

Remove parenthesis around (4x)
-28ln + 2lnx = ln * 4x

Reorder the terms for easier multiplication:
-28ln + 2lnx = 4ln * x

Multiply ln * x
-28ln + 2lnx = 4lnx

Solving
-28ln + 2lnx = 4lnx

Solving for variable 'l'.

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

Add '-4lnx' to each side of the equation.
-28ln + 2lnx + -4lnx = 4lnx + -4lnx

Combine like terms: 2lnx + -4lnx = -2lnx
-28ln + -2lnx = 4lnx + -4lnx

Combine like terms: 4lnx + -4lnx = 0
-28ln + -2lnx = 0

Factor out the Greatest Common Factor (GCF), '-2ln'.
-2ln(14 + x) = 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 '(14 + x)' equal to zero and attempt to solve: Simplifying 14 + x = 0 Solving 14 + x = 0 Move all terms containing l to the left, all other terms to the right. Add '-14' to each side of the equation. 14 + -14 + x = 0 + -14 Combine like terms: 14 + -14 = 0 0 + x = 0 + -14 x = 0 + -14 Combine like terms: 0 + -14 = -14 x = -14 Add '-1x' to each side of the equation. x + -1x = -14 + -1x Combine like terms: x + -1x = 0 0 = -14 + -1x Simplifying 0 = -14 + -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.
