Solution for ln(1-x)+ln(8-x)=ln(18) equation:


Simplifying
ln(1 + -1x) + ln(8 + -1x) = ln(18)
(1 * ln + -1x * ln) + ln(8 + -1x) = ln(18)
(1ln + -1lnx) + ln(8 + -1x) = ln(18)
1ln + -1lnx + (8 * ln + -1x * ln) = ln(18)
1ln + -1lnx + (8ln + -1lnx) = ln(18)

Reorder the terms:
1ln + 8ln + -1lnx + -1lnx = ln(18)

Combine like terms: 1ln + 8ln = 9ln
9ln + -1lnx + -1lnx = ln(18)

Combine like terms: -1lnx + -1lnx = -2lnx
9ln + -2lnx = ln(18)

Reorder the terms for easier multiplication:
9ln + -2lnx = 18ln

Solving
9ln + -2lnx = 18ln

Solving for variable 'l'.

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

Add '-18ln' to each side of the equation.
9ln + -18ln + -2lnx = 18ln + -18ln

Combine like terms: 9ln + -18ln = -9ln
-9ln + -2lnx = 18ln + -18ln

Combine like terms: 18ln + -18ln = 0
-9ln + -2lnx = 0

Factor out the Greatest Common Factor (GCF), '-1ln'.
-1ln(9 + 2x) = 0

Ignore the factor -1.

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 '(9 + 2x)' equal to zero and attempt to solve: Simplifying 9 + 2x = 0 Solving 9 + 2x = 0 Move all terms containing l to the left, all other terms to the right. Add '-9' to each side of the equation. 9 + -9 + 2x = 0 + -9 Combine like terms: 9 + -9 = 0 0 + 2x = 0 + -9 2x = 0 + -9 Combine like terms: 0 + -9 = -9 2x = -9 Add '-2x' to each side of the equation. 2x + -2x = -9 + -2x Combine like terms: 2x + -2x = 0 0 = -9 + -2x Simplifying 0 = -9 + -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.
