Solution for ln(5x)-ln(x-2)=ln(8) equation:


Simplifying
ln(5x) + -1ln(x + -2) = ln(8)

Remove parenthesis around (5x)
ln * 5x + -1ln(x + -2) = ln(8)

Reorder the terms for easier multiplication:
5ln * x + -1ln(x + -2) = ln(8)

Multiply ln * x
5lnx + -1ln(x + -2) = ln(8)

Reorder the terms:
5lnx + -1ln(-2 + x) = ln(8)
5lnx + (-2 * -1ln + x * -1ln) = ln(8)
5lnx + (2ln + -1lnx) = ln(8)

Reorder the terms:
2ln + 5lnx + -1lnx = ln(8)

Combine like terms: 5lnx + -1lnx = 4lnx
2ln + 4lnx = ln(8)

Reorder the terms for easier multiplication:
2ln + 4lnx = 8ln

Solving
2ln + 4lnx = 8ln

Solving for variable 'l'.

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

Add '-8ln' to each side of the equation.
2ln + -8ln + 4lnx = 8ln + -8ln

Combine like terms: 2ln + -8ln = -6ln
-6ln + 4lnx = 8ln + -8ln

Combine like terms: 8ln + -8ln = 0
-6ln + 4lnx = 0

Factor out the Greatest Common Factor (GCF), '2ln'.
2ln(-3 + 2x) = 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 '(-3 + 2x)' equal to zero and attempt to solve: Simplifying -3 + 2x = 0 Solving -3 + 2x = 0 Move all terms containing l to the left, all other terms to the right. Add '3' to each side of the equation. -3 + 3 + 2x = 0 + 3 Combine like terms: -3 + 3 = 0 0 + 2x = 0 + 3 2x = 0 + 3 Combine like terms: 0 + 3 = 3 2x = 3 Add '-2x' to each side of the equation. 2x + -2x = 3 + -2x Combine like terms: 2x + -2x = 0 0 = 3 + -2x Simplifying 0 = 3 + -2x 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.
