Solution for ln(5x+6)=ln(x+4)+ln(3) equation:


Simplifying
ln(5x + 6) = ln(x + 4) + ln(3)

Reorder the terms:
ln(6 + 5x) = ln(x + 4) + ln(3)
(6 * ln + 5x * ln) = ln(x + 4) + ln(3)
(6ln + 5lnx) = ln(x + 4) + ln(3)

Reorder the terms:
6ln + 5lnx = ln(4 + x) + ln(3)
6ln + 5lnx = (4 * ln + x * ln) + ln(3)
6ln + 5lnx = (4ln + lnx) + ln(3)

Reorder the terms for easier multiplication:
6ln + 5lnx = 4ln + lnx + 3ln

Reorder the terms:
6ln + 5lnx = 4ln + 3ln + lnx

Combine like terms: 4ln + 3ln = 7ln
6ln + 5lnx = 7ln + lnx

Solving
6ln + 5lnx = 7ln + lnx

Solving for variable 'l'.

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

Add '-7ln' to each side of the equation.
6ln + -7ln + 5lnx = 7ln + -7ln + lnx

Combine like terms: 6ln + -7ln = -1ln
-1ln + 5lnx = 7ln + -7ln + lnx

Combine like terms: 7ln + -7ln = 0
-1ln + 5lnx = 0 + lnx
-1ln + 5lnx = lnx

Add '-1lnx' to each side of the equation.
-1ln + 5lnx + -1lnx = lnx + -1lnx

Combine like terms: 5lnx + -1lnx = 4lnx
-1ln + 4lnx = lnx + -1lnx

Combine like terms: lnx + -1lnx = 0
-1ln + 4lnx = 0

Factor out the Greatest Common Factor (GCF), 'ln'.
ln(-1 + 4x) = 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 + 4x)' equal to zero and attempt to solve: Simplifying -1 + 4x = 0 Solving -1 + 4x = 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 + 4x = 0 + 1 Combine like terms: -1 + 1 = 0 0 + 4x = 0 + 1 4x = 0 + 1 Combine like terms: 0 + 1 = 1 4x = 1 Add '-4x' to each side of the equation. 4x + -4x = 1 + -4x Combine like terms: 4x + -4x = 0 0 = 1 + -4x Simplifying 0 = 1 + -4x 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.
