Solution for ln(x-4)+ln(x+3)=ln(x-13) equation:


Simplifying
ln(x + -4) + ln(x + 3) = ln(x + -13)

Reorder the terms:
ln(-4 + x) + ln(x + 3) = ln(x + -13)
(-4 * ln + x * ln) + ln(x + 3) = ln(x + -13)
(-4ln + lnx) + ln(x + 3) = ln(x + -13)

Reorder the terms:
-4ln + lnx + ln(3 + x) = ln(x + -13)
-4ln + lnx + (3 * ln + x * ln) = ln(x + -13)
-4ln + lnx + (3ln + lnx) = ln(x + -13)

Reorder the terms:
-4ln + 3ln + lnx + lnx = ln(x + -13)

Combine like terms: -4ln + 3ln = -1ln
-1ln + lnx + lnx = ln(x + -13)

Combine like terms: lnx + lnx = 2lnx
-1ln + 2lnx = ln(x + -13)

Reorder the terms:
-1ln + 2lnx = ln(-13 + x)
-1ln + 2lnx = (-13 * ln + x * ln)
-1ln + 2lnx = (-13ln + lnx)

Solving
-1ln + 2lnx = -13ln + lnx

Solving for variable 'l'.

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

Add '13ln' to each side of the equation.
-1ln + 13ln + 2lnx = -13ln + 13ln + lnx

Combine like terms: -1ln + 13ln = 12ln
12ln + 2lnx = -13ln + 13ln + lnx

Combine like terms: -13ln + 13ln = 0
12ln + 2lnx = 0 + lnx
12ln + 2lnx = lnx

Add '-1lnx' to each side of the equation.
12ln + 2lnx + -1lnx = lnx + -1lnx

Combine like terms: 2lnx + -1lnx = 1lnx
12ln + 1lnx = lnx + -1lnx

Combine like terms: lnx + -1lnx = 0
12ln + 1lnx = 0

Factor out the Greatest Common Factor (GCF), 'ln'.
ln(12 + x) = 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 '(12 + x)' equal to zero and attempt to solve: Simplifying 12 + x = 0 Solving 12 + x = 0 Move all terms containing l to the left, all other terms to the right. Add '-12' to each side of the equation. 12 + -12 + x = 0 + -12 Combine like terms: 12 + -12 = 0 0 + x = 0 + -12 x = 0 + -12 Combine like terms: 0 + -12 = -12 x = -12 Add '-1x' to each side of the equation. x + -1x = -12 + -1x Combine like terms: x + -1x = 0 0 = -12 + -1x Simplifying 0 = -12 + -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.
