Solution for ln(5-x)+ln(-3-x)=ln(3-9x) equation:


Simplifying
ln(5 + -1x) + ln(-3 + -1x) = ln(3 + -9x)
(5 * ln + -1x * ln) + ln(-3 + -1x) = ln(3 + -9x)
(5ln + -1lnx) + ln(-3 + -1x) = ln(3 + -9x)
5ln + -1lnx + (-3 * ln + -1x * ln) = ln(3 + -9x)
5ln + -1lnx + (-3ln + -1lnx) = ln(3 + -9x)

Reorder the terms:
5ln + -3ln + -1lnx + -1lnx = ln(3 + -9x)

Combine like terms: 5ln + -3ln = 2ln
2ln + -1lnx + -1lnx = ln(3 + -9x)

Combine like terms: -1lnx + -1lnx = -2lnx
2ln + -2lnx = ln(3 + -9x)
2ln + -2lnx = (3 * ln + -9x * ln)
2ln + -2lnx = (3ln + -9lnx)

Solving
2ln + -2lnx = 3ln + -9lnx

Solving for variable 'l'.

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

Add '-3ln' to each side of the equation.
2ln + -3ln + -2lnx = 3ln + -3ln + -9lnx

Combine like terms: 2ln + -3ln = -1ln
-1ln + -2lnx = 3ln + -3ln + -9lnx

Combine like terms: 3ln + -3ln = 0
-1ln + -2lnx = 0 + -9lnx
-1ln + -2lnx = -9lnx

Add '9lnx' to each side of the equation.
-1ln + -2lnx + 9lnx = -9lnx + 9lnx

Combine like terms: -2lnx + 9lnx = 7lnx
-1ln + 7lnx = -9lnx + 9lnx

Combine like terms: -9lnx + 9lnx = 0
-1ln + 7lnx = 0

Factor out the Greatest Common Factor (GCF), 'ln'.
ln(-1 + 7x) = 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 '(-1 + 7x)' equal to zero and attempt to solve: Simplifying -1 + 7x = 0 Solving -1 + 7x = 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 + 7x = 0 + 1 Combine like terms: -1 + 1 = 0 0 + 7x = 0 + 1 7x = 0 + 1 Combine like terms: 0 + 1 = 1 7x = 1 Add '-7x' to each side of the equation. 7x + -7x = 1 + -7x Combine like terms: 7x + -7x = 0 0 = 1 + -7x Simplifying 0 = 1 + -7x 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.
