Solution for 2ln(x-4)=ln(10x) equation:


Simplifying
2ln(x + -4) = ln(10x)

Reorder the terms:
2ln(-4 + x) = ln(10x)
(-4 * 2ln + x * 2ln) = ln(10x)
(-8ln + 2lnx) = ln(10x)

Remove parenthesis around (10x)
-8ln + 2lnx = ln * 10x

Reorder the terms for easier multiplication:
-8ln + 2lnx = 10ln * x

Multiply ln * x
-8ln + 2lnx = 10lnx

Solving
-8ln + 2lnx = 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.
-8ln + 2lnx + -10lnx = 10lnx + -10lnx

Combine like terms: 2lnx + -10lnx = -8lnx
-8ln + -8lnx = 10lnx + -10lnx

Combine like terms: 10lnx + -10lnx = 0
-8ln + -8lnx = 0

Factor out the Greatest Common Factor (GCF), '-8ln'.
-8ln(1 + x) = 0

Ignore the factor -8.

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