Solution for 2ln(1-x)-ln(7-x)=0 equation:


Simplifying
2ln(1 + -1x) + -1ln(7 + -1x) = 0
(1 * 2ln + -1x * 2ln) + -1ln(7 + -1x) = 0
(2ln + -2lnx) + -1ln(7 + -1x) = 0
2ln + -2lnx + (7 * -1ln + -1x * -1ln) = 0
2ln + -2lnx + (-7ln + 1lnx) = 0

Reorder the terms:
2ln + -7ln + -2lnx + 1lnx = 0

Combine like terms: 2ln + -7ln = -5ln
-5ln + -2lnx + 1lnx = 0

Combine like terms: -2lnx + 1lnx = -1lnx
-5ln + -1lnx = 0

Solving
-5ln + -1lnx = 0

Solving for variable 'l'.

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

Factor out the Greatest Common Factor (GCF), '-1ln'.
-1ln(5 + x) = 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 '(5 + x)' equal to zero and attempt to solve: Simplifying 5 + x = 0 Solving 5 + x = 0 Move all terms containing l to the left, all other terms to the right. Add '-5' to each side of the equation. 5 + -5 + x = 0 + -5 Combine like terms: 5 + -5 = 0 0 + x = 0 + -5 x = 0 + -5 Combine like terms: 0 + -5 = -5 x = -5 Add '-1x' to each side of the equation. x + -1x = -5 + -1x Combine like terms: x + -1x = 0 0 = -5 + -1x Simplifying 0 = -5 + -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.
