Solution for ln(x-7)+ln(x+9)=ln(36) equation:


Simplifying
ln(x + -7) + ln(x + 9) = ln(36)

Reorder the terms:
ln(-7 + x) + ln(x + 9) = ln(36)
(-7 * ln + x * ln) + ln(x + 9) = ln(36)
(-7ln + lnx) + ln(x + 9) = ln(36)

Reorder the terms:
-7ln + lnx + ln(9 + x) = ln(36)
-7ln + lnx + (9 * ln + x * ln) = ln(36)
-7ln + lnx + (9ln + lnx) = ln(36)

Reorder the terms:
-7ln + 9ln + lnx + lnx = ln(36)

Combine like terms: -7ln + 9ln = 2ln
2ln + lnx + lnx = ln(36)

Combine like terms: lnx + lnx = 2lnx
2ln + 2lnx = ln(36)

Reorder the terms for easier multiplication:
2ln + 2lnx = 36ln

Solving
2ln + 2lnx = 36ln

Solving for variable 'l'.

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

Add '-36ln' to each side of the equation.
2ln + -36ln + 2lnx = 36ln + -36ln

Combine like terms: 2ln + -36ln = -34ln
-34ln + 2lnx = 36ln + -36ln

Combine like terms: 36ln + -36ln = 0
-34ln + 2lnx = 0

Factor out the Greatest Common Factor (GCF), '2ln'.
2ln(-17 + x) = 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 '(-17 + x)' equal to zero and attempt to solve: Simplifying -17 + x = 0 Solving -17 + x = 0 Move all terms containing l to the left, all other terms to the right. Add '17' to each side of the equation. -17 + 17 + x = 0 + 17 Combine like terms: -17 + 17 = 0 0 + x = 0 + 17 x = 0 + 17 Combine like terms: 0 + 17 = 17 x = 17 Add '-1x' to each side of the equation. x + -1x = 17 + -1x Combine like terms: x + -1x = 0 0 = 17 + -1x Simplifying 0 = 17 + -1x 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.
