Solution for ln(x-8)+ln(x+18)=3ln(3) equation:


Simplifying
ln(x + -8) + ln(x + 18) = 3ln(3)

Reorder the terms:
ln(-8 + x) + ln(x + 18) = 3ln(3)
(-8 * ln + x * ln) + ln(x + 18) = 3ln(3)
(-8ln + lnx) + ln(x + 18) = 3ln(3)

Reorder the terms:
-8ln + lnx + ln(18 + x) = 3ln(3)
-8ln + lnx + (18 * ln + x * ln) = 3ln(3)
-8ln + lnx + (18ln + lnx) = 3ln(3)

Reorder the terms:
-8ln + 18ln + lnx + lnx = 3ln(3)

Combine like terms: -8ln + 18ln = 10ln
10ln + lnx + lnx = 3ln(3)

Combine like terms: lnx + lnx = 2lnx
10ln + 2lnx = 3ln(3)

Reorder the terms for easier multiplication:
10ln + 2lnx = 3 * 3ln

Multiply 3 * 3
10ln + 2lnx = 9ln

Solving
10ln + 2lnx = 9ln

Solving for variable 'l'.

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

Add '-9ln' to each side of the equation.
10ln + -9ln + 2lnx = 9ln + -9ln

Combine like terms: 10ln + -9ln = 1ln
1ln + 2lnx = 9ln + -9ln

Combine like terms: 9ln + -9ln = 0
1ln + 2lnx = 0

Factor out the Greatest Common Factor (GCF), 'ln'.
ln(1 + 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 '(1 + 2x)' equal to zero and attempt to solve: Simplifying 1 + 2x = 0 Solving 1 + 2x = 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 + 2x = 0 + -1 Combine like terms: 1 + -1 = 0 0 + 2x = 0 + -1 2x = 0 + -1 Combine like terms: 0 + -1 = -1 2x = -1 Add '-2x' to each side of the equation. 2x + -2x = -1 + -2x Combine like terms: 2x + -2x = 0 0 = -1 + -2x Simplifying 0 = -1 + -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.
