Solution for ln(x-5)+ln(x+2)=ln(x-14) equation:


Simplifying
ln(x + -5) + ln(x + 2) = ln(x + -14)

Reorder the terms:
ln(-5 + x) + ln(x + 2) = ln(x + -14)
(-5 * ln + x * ln) + ln(x + 2) = ln(x + -14)
(-5ln + lnx) + ln(x + 2) = ln(x + -14)

Reorder the terms:
-5ln + lnx + ln(2 + x) = ln(x + -14)
-5ln + lnx + (2 * ln + x * ln) = ln(x + -14)
-5ln + lnx + (2ln + lnx) = ln(x + -14)

Reorder the terms:
-5ln + 2ln + lnx + lnx = ln(x + -14)

Combine like terms: -5ln + 2ln = -3ln
-3ln + lnx + lnx = ln(x + -14)

Combine like terms: lnx + lnx = 2lnx
-3ln + 2lnx = ln(x + -14)

Reorder the terms:
-3ln + 2lnx = ln(-14 + x)
-3ln + 2lnx = (-14 * ln + x * ln)
-3ln + 2lnx = (-14ln + lnx)

Solving
-3ln + 2lnx = -14ln + lnx

Solving for variable 'l'.

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

Add '14ln' to each side of the equation.
-3ln + 14ln + 2lnx = -14ln + 14ln + lnx

Combine like terms: -3ln + 14ln = 11ln
11ln + 2lnx = -14ln + 14ln + lnx

Combine like terms: -14ln + 14ln = 0
11ln + 2lnx = 0 + lnx
11ln + 2lnx = lnx

Add '-1lnx' to each side of the equation.
11ln + 2lnx + -1lnx = lnx + -1lnx

Combine like terms: 2lnx + -1lnx = 1lnx
11ln + 1lnx = lnx + -1lnx

Combine like terms: lnx + -1lnx = 0
11ln + 1lnx = 0

Factor out the Greatest Common Factor (GCF), 'ln'.
ln(11 + 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 '(11 + x)' equal to zero and attempt to solve: Simplifying 11 + x = 0 Solving 11 + x = 0 Move all terms containing l to the left, all other terms to the right. Add '-11' to each side of the equation. 11 + -11 + x = 0 + -11 Combine like terms: 11 + -11 = 0 0 + x = 0 + -11 x = 0 + -11 Combine like terms: 0 + -11 = -11 x = -11 Add '-1x' to each side of the equation. x + -1x = -11 + -1x Combine like terms: x + -1x = 0 0 = -11 + -1x Simplifying 0 = -11 + -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.
