Solution for ln(x+7)+ln(x+5)=ln(5) equation:


Simplifying
ln(x + 7) + ln(x + 5) = ln(5)

Reorder the terms:
ln(7 + x) + ln(x + 5) = ln(5)
(7 * ln + x * ln) + ln(x + 5) = ln(5)
(7ln + lnx) + ln(x + 5) = ln(5)

Reorder the terms:
7ln + lnx + ln(5 + x) = ln(5)
7ln + lnx + (5 * ln + x * ln) = ln(5)
7ln + lnx + (5ln + lnx) = ln(5)

Reorder the terms:
7ln + 5ln + lnx + lnx = ln(5)

Combine like terms: 7ln + 5ln = 12ln
12ln + lnx + lnx = ln(5)

Combine like terms: lnx + lnx = 2lnx
12ln + 2lnx = ln(5)

Reorder the terms for easier multiplication:
12ln + 2lnx = 5ln

Solving
12ln + 2lnx = 5ln

Solving for variable 'l'.

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

Add '-5ln' to each side of the equation.
12ln + -5ln + 2lnx = 5ln + -5ln

Combine like terms: 12ln + -5ln = 7ln
7ln + 2lnx = 5ln + -5ln

Combine like terms: 5ln + -5ln = 0
7ln + 2lnx = 0

Factor out the Greatest Common Factor (GCF), 'ln'.
ln(7 + 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 '(7 + 2x)' equal to zero and attempt to solve: Simplifying 7 + 2x = 0 Solving 7 + 2x = 0 Move all terms containing l to the left, all other terms to the right. Add '-7' to each side of the equation. 7 + -7 + 2x = 0 + -7 Combine like terms: 7 + -7 = 0 0 + 2x = 0 + -7 2x = 0 + -7 Combine like terms: 0 + -7 = -7 2x = -7 Add '-2x' to each side of the equation. 2x + -2x = -7 + -2x Combine like terms: 2x + -2x = 0 0 = -7 + -2x Simplifying 0 = -7 + -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.
