Solution for ln(x+6)=ln(2x+5) equation:


Simplifying
ln(x + 6) = ln(2x + 5)

Reorder the terms:
ln(6 + x) = ln(2x + 5)
(6 * ln + x * ln) = ln(2x + 5)
(6ln + lnx) = ln(2x + 5)

Reorder the terms:
6ln + lnx = ln(5 + 2x)
6ln + lnx = (5 * ln + 2x * ln)
6ln + lnx = (5ln + 2lnx)

Solving
6ln + lnx = 5ln + 2lnx

Solving for variable 'l'.

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

Add '-5ln' to each side of the equation.
6ln + -5ln + lnx = 5ln + -5ln + 2lnx

Combine like terms: 6ln + -5ln = 1ln
1ln + lnx = 5ln + -5ln + 2lnx

Combine like terms: 5ln + -5ln = 0
1ln + lnx = 0 + 2lnx
1ln + lnx = 2lnx

Add '-2lnx' to each side of the equation.
1ln + lnx + -2lnx = 2lnx + -2lnx

Combine like terms: lnx + -2lnx = -1lnx
1ln + -1lnx = 2lnx + -2lnx

Combine like terms: 2lnx + -2lnx = 0
1ln + -1lnx = 0

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