Solution for ln(x+9)=ln(4x+36)-lnx equation:


Simplifying
ln(x + 9) = ln(4x + 36) + -1lnx

Reorder the terms:
ln(9 + x) = ln(4x + 36) + -1lnx
(9 * ln + x * ln) = ln(4x + 36) + -1lnx
(9ln + lnx) = ln(4x + 36) + -1lnx

Reorder the terms:
9ln + lnx = ln(36 + 4x) + -1lnx
9ln + lnx = (36 * ln + 4x * ln) + -1lnx
9ln + lnx = (36ln + 4lnx) + -1lnx

Combine like terms: 4lnx + -1lnx = 3lnx
9ln + lnx = 36ln + 3lnx

Solving
9ln + lnx = 36ln + 3lnx

Solving for variable 'l'.

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

Add '-36ln' to each side of the equation.
9ln + -36ln + lnx = 36ln + -36ln + 3lnx

Combine like terms: 9ln + -36ln = -27ln
-27ln + lnx = 36ln + -36ln + 3lnx

Combine like terms: 36ln + -36ln = 0
-27ln + lnx = 0 + 3lnx
-27ln + lnx = 3lnx

Add '-3lnx' to each side of the equation.
-27ln + lnx + -3lnx = 3lnx + -3lnx

Combine like terms: lnx + -3lnx = -2lnx
-27ln + -2lnx = 3lnx + -3lnx

Combine like terms: 3lnx + -3lnx = 0
-27ln + -2lnx = 0

Factor out the Greatest Common Factor (GCF), '-1ln'.
-1ln(27 + 2x) = 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 '(27 + 2x)' equal to zero and attempt to solve: Simplifying 27 + 2x = 0 Solving 27 + 2x = 0 Move all terms containing l to the left, all other terms to the right. Add '-27' to each side of the equation. 27 + -27 + 2x = 0 + -27 Combine like terms: 27 + -27 = 0 0 + 2x = 0 + -27 2x = 0 + -27 Combine like terms: 0 + -27 = -27 2x = -27 Add '-2x' to each side of the equation. 2x + -2x = -27 + -2x Combine like terms: 2x + -2x = 0 0 = -27 + -2x Simplifying 0 = -27 + -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.
