Solution for ln(4x-5)=ln(2x-11) equation:


Simplifying
ln(4x + -5) = ln(2x + -11)

Reorder the terms:
ln(-5 + 4x) = ln(2x + -11)
(-5 * ln + 4x * ln) = ln(2x + -11)
(-5ln + 4lnx) = ln(2x + -11)

Reorder the terms:
-5ln + 4lnx = ln(-11 + 2x)
-5ln + 4lnx = (-11 * ln + 2x * ln)
-5ln + 4lnx = (-11ln + 2lnx)

Solving
-5ln + 4lnx = -11ln + 2lnx

Solving for variable 'l'.

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

Add '11ln' to each side of the equation.
-5ln + 11ln + 4lnx = -11ln + 11ln + 2lnx

Combine like terms: -5ln + 11ln = 6ln
6ln + 4lnx = -11ln + 11ln + 2lnx

Combine like terms: -11ln + 11ln = 0
6ln + 4lnx = 0 + 2lnx
6ln + 4lnx = 2lnx

Add '-2lnx' to each side of the equation.
6ln + 4lnx + -2lnx = 2lnx + -2lnx

Combine like terms: 4lnx + -2lnx = 2lnx
6ln + 2lnx = 2lnx + -2lnx

Combine like terms: 2lnx + -2lnx = 0
6ln + 2lnx = 0

Factor out the Greatest Common Factor (GCF), '2ln'.
2ln(3 + x) = 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 '(3 + x)' equal to zero and attempt to solve: Simplifying 3 + x = 0 Solving 3 + x = 0 Move all terms containing l to the left, all other terms to the right. Add '-3' to each side of the equation. 3 + -3 + x = 0 + -3 Combine like terms: 3 + -3 = 0 0 + x = 0 + -3 x = 0 + -3 Combine like terms: 0 + -3 = -3 x = -3 Add '-1x' to each side of the equation. x + -1x = -3 + -1x Combine like terms: x + -1x = 0 0 = -3 + -1x Simplifying 0 = -3 + -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.
