Solution for ln(10x+2x)=2ln(x+1) equation:


Simplifying
ln(10x + 2x) = 2ln(x + 1)

Combine like terms: 10x + 2x = 12x
ln(12x) = 2ln(x + 1)

Remove parenthesis around (12x)
ln * 12x = 2ln(x + 1)

Reorder the terms for easier multiplication:
12ln * x = 2ln(x + 1)

Multiply ln * x
12lnx = 2ln(x + 1)

Reorder the terms:
12lnx = 2ln(1 + x)
12lnx = (1 * 2ln + x * 2ln)
12lnx = (2ln + 2lnx)

Solving
12lnx = 2ln + 2lnx

Solving for variable 'l'.

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

Add '-2ln' to each side of the equation.
-2ln + 12lnx = 2ln + -2ln + 2lnx

Combine like terms: 2ln + -2ln = 0
-2ln + 12lnx = 0 + 2lnx
-2ln + 12lnx = 2lnx

Add '-2lnx' to each side of the equation.
-2ln + 12lnx + -2lnx = 2lnx + -2lnx

Combine like terms: 12lnx + -2lnx = 10lnx
-2ln + 10lnx = 2lnx + -2lnx

Combine like terms: 2lnx + -2lnx = 0
-2ln + 10lnx = 0

Factor out the Greatest Common Factor (GCF), '2ln'.
2ln(-1 + 5x) = 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 '(-1 + 5x)' equal to zero and attempt to solve: Simplifying -1 + 5x = 0 Solving -1 + 5x = 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 + 5x = 0 + 1 Combine like terms: -1 + 1 = 0 0 + 5x = 0 + 1 5x = 0 + 1 Combine like terms: 0 + 1 = 1 5x = 1 Add '-5x' to each side of the equation. 5x + -5x = 1 + -5x Combine like terms: 5x + -5x = 0 0 = 1 + -5x Simplifying 0 = 1 + -5x 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.
