Solution for ln(x+3)+ln(x-3)=ln(27) equation:


Simplifying
ln(x + 3) + ln(x + -3) = ln(27)

Reorder the terms:
ln(3 + x) + ln(x + -3) = ln(27)
(3 * ln + x * ln) + ln(x + -3) = ln(27)
(3ln + lnx) + ln(x + -3) = ln(27)

Reorder the terms:
3ln + lnx + ln(-3 + x) = ln(27)
3ln + lnx + (-3 * ln + x * ln) = ln(27)
3ln + lnx + (-3ln + lnx) = ln(27)

Reorder the terms:
3ln + -3ln + lnx + lnx = ln(27)

Combine like terms: 3ln + -3ln = 0
0 + lnx + lnx = ln(27)
lnx + lnx = ln(27)

Combine like terms: lnx + lnx = 2lnx
2lnx = ln(27)

Reorder the terms for easier multiplication:
2lnx = 27ln

Solving
2lnx = 27ln

Solving for variable 'l'.

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

Add '-27ln' to each side of the equation.
-27ln + 2lnx = 27ln + -27ln

Combine like terms: 27ln + -27ln = 0
-27ln + 2lnx = 0

Factor out the Greatest Common Factor (GCF), 'ln'.
ln(-27 + 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 '(-27 + 2x)' equal to zero and attempt to solve: Simplifying -27 + 2x = 0 Solving -27 + 2x = 0 Move all terms containing l to the left, all other terms to the right. Add '27' to each side of the equation. -27 + 27 + 2x = 0 + 27 Combine like terms: -27 + 27 = 0 0 + 2x = 0 + 27 2x = 0 + 27 Combine like terms: 0 + 27 = 27 2x = 27 Add '-2x' to each side of the equation. 2x + -2x = 27 + -2x Combine like terms: 2x + -2x = 0 0 = 27 + -2x Simplifying 0 = 27 + -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.
