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


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

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

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

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

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

Reorder the terms for easier multiplication:
7ln + 6lnx = 3ln

Solving
7ln + 6lnx = 3ln

Solving for variable 'l'.

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

Add '-3ln' to each side of the equation.
7ln + -3ln + 6lnx = 3ln + -3ln

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

Combine like terms: 3ln + -3ln = 0
4ln + 6lnx = 0

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