Solution for ln(4x+1)-ln(x-2)=lnx equation:


Simplifying
ln(4x + 1) + -1ln(x + -2) = lnx

Reorder the terms:
ln(1 + 4x) + -1ln(x + -2) = lnx
(1 * ln + 4x * ln) + -1ln(x + -2) = lnx
(1ln + 4lnx) + -1ln(x + -2) = lnx

Reorder the terms:
1ln + 4lnx + -1ln(-2 + x) = lnx
1ln + 4lnx + (-2 * -1ln + x * -1ln) = lnx
1ln + 4lnx + (2ln + -1lnx) = lnx

Reorder the terms:
1ln + 2ln + 4lnx + -1lnx = lnx

Combine like terms: 1ln + 2ln = 3ln
3ln + 4lnx + -1lnx = lnx

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

Solving
3ln + 3lnx = lnx

Solving for variable 'l'.

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

Add '-1lnx' to each side of the equation.
3ln + 3lnx + -1lnx = lnx + -1lnx

Combine like terms: 3lnx + -1lnx = 2lnx
3ln + 2lnx = lnx + -1lnx

Combine like terms: lnx + -1lnx = 0
3ln + 2lnx = 0

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