Solution for ln(x-5)=ln(10x) equation:


Simplifying
ln(x + -5) = ln(10x)

Reorder the terms:
ln(-5 + x) = ln(10x)
(-5 * ln + x * ln) = ln(10x)
(-5ln + lnx) = ln(10x)

Remove parenthesis around (10x)
-5ln + lnx = ln * 10x

Reorder the terms for easier multiplication:
-5ln + lnx = 10ln * x

Multiply ln * x
-5ln + lnx = 10lnx

Solving
-5ln + lnx = 10lnx

Solving for variable 'l'.

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

Add '-10lnx' to each side of the equation.
-5ln + lnx + -10lnx = 10lnx + -10lnx

Combine like terms: lnx + -10lnx = -9lnx
-5ln + -9lnx = 10lnx + -10lnx

Combine like terms: 10lnx + -10lnx = 0
-5ln + -9lnx = 0

Factor out the Greatest Common Factor (GCF), '-1ln'.
-1ln(5 + 9x) = 0

Ignore the factor -1.

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 '(5 + 9x)' equal to zero and attempt to solve: Simplifying 5 + 9x = 0 Solving 5 + 9x = 0 Move all terms containing l to the left, all other terms to the right. Add '-5' to each side of the equation. 5 + -5 + 9x = 0 + -5 Combine like terms: 5 + -5 = 0 0 + 9x = 0 + -5 9x = 0 + -5 Combine like terms: 0 + -5 = -5 9x = -5 Add '-9x' to each side of the equation. 9x + -9x = -5 + -9x Combine like terms: 9x + -9x = 0 0 = -5 + -9x Simplifying 0 = -5 + -9x 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.
