Solution for ln(9)=ln(x-8)-ln(16) equation:


Simplifying
ln(9) = ln(x + -8) + -1ln(16)

Reorder the terms for easier multiplication:
9ln = ln(x + -8) + -1ln(16)

Reorder the terms:
9ln = ln(-8 + x) + -1ln(16)
9ln = (-8 * ln + x * ln) + -1ln(16)
9ln = (-8ln + lnx) + -1ln(16)

Reorder the terms for easier multiplication:
9ln = -8ln + lnx + -1 * 16ln

Multiply -1 * 16
9ln = -8ln + lnx + -16ln

Reorder the terms:
9ln = -8ln + -16ln + lnx

Combine like terms: -8ln + -16ln = -24ln
9ln = -24ln + lnx

Solving
9ln = -24ln + lnx

Solving for variable 'l'.

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

Add '24ln' to each side of the equation.
9ln + 24ln = -24ln + 24ln + lnx

Combine like terms: 9ln + 24ln = 33ln
33ln = -24ln + 24ln + lnx

Combine like terms: -24ln + 24ln = 0
33ln = 0 + lnx
33ln = lnx

Add '-1lnx' to each side of the equation.
33ln + -1lnx = lnx + -1lnx

Combine like terms: lnx + -1lnx = 0
33ln + -1lnx = 0

Factor out the Greatest Common Factor (GCF), 'ln'.
ln(33 + -1x) = 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 '(33 + -1x)' equal to zero and attempt to solve: Simplifying 33 + -1x = 0 Solving 33 + -1x = 0 Move all terms containing l to the left, all other terms to the right. Add '-33' to each side of the equation. 33 + -33 + -1x = 0 + -33 Combine like terms: 33 + -33 = 0 0 + -1x = 0 + -33 -1x = 0 + -33 Combine like terms: 0 + -33 = -33 -1x = -33 Add 'x' to each side of the equation. -1x + x = -33 + x Combine like terms: -1x + x = 0 0 = -33 + x Simplifying 0 = -33 + x 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.
