Solution for ln(5x+1)=2(ln(4x-1)) equation:


Simplifying
ln(5x + 1) = 2(ln(4x + -1))

Reorder the terms:
ln(1 + 5x) = 2(ln(4x + -1))
(1 * ln + 5x * ln) = 2(ln(4x + -1))
(1ln + 5lnx) = 2(ln(4x + -1))

Reorder the terms:
1ln + 5lnx = 2(ln(-1 + 4x))
1ln + 5lnx = 2((-1 * ln + 4x * ln))
1ln + 5lnx = 2((-1ln + 4lnx))
1ln + 5lnx = (-1ln * 2 + 4lnx * 2)
1ln + 5lnx = (-2ln + 8lnx)

Solving
1ln + 5lnx = -2ln + 8lnx

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.
1ln + 2ln + 5lnx = -2ln + 2ln + 8lnx

Combine like terms: 1ln + 2ln = 3ln
3ln + 5lnx = -2ln + 2ln + 8lnx

Combine like terms: -2ln + 2ln = 0
3ln + 5lnx = 0 + 8lnx
3ln + 5lnx = 8lnx

Add '-8lnx' to each side of the equation.
3ln + 5lnx + -8lnx = 8lnx + -8lnx

Combine like terms: 5lnx + -8lnx = -3lnx
3ln + -3lnx = 8lnx + -8lnx

Combine like terms: 8lnx + -8lnx = 0
3ln + -3lnx = 0

Factor out the Greatest Common Factor (GCF), '3ln'.
3ln(1 + -1x) = 0

Ignore the factor 3.

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.
