Solution for ln(7-x)+ln(1-x)=ln(25-x) equation:


Simplifying
ln(7 + -1x) + ln(1 + -1x) = ln(25 + -1x)
(7 * ln + -1x * ln) + ln(1 + -1x) = ln(25 + -1x)
(7ln + -1lnx) + ln(1 + -1x) = ln(25 + -1x)
7ln + -1lnx + (1 * ln + -1x * ln) = ln(25 + -1x)
7ln + -1lnx + (1ln + -1lnx) = ln(25 + -1x)

Reorder the terms:
7ln + 1ln + -1lnx + -1lnx = ln(25 + -1x)

Combine like terms: 7ln + 1ln = 8ln
8ln + -1lnx + -1lnx = ln(25 + -1x)

Combine like terms: -1lnx + -1lnx = -2lnx
8ln + -2lnx = ln(25 + -1x)
8ln + -2lnx = (25 * ln + -1x * ln)
8ln + -2lnx = (25ln + -1lnx)

Solving
8ln + -2lnx = 25ln + -1lnx

Solving for variable 'l'.

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

Add '-25ln' to each side of the equation.
8ln + -25ln + -2lnx = 25ln + -25ln + -1lnx

Combine like terms: 8ln + -25ln = -17ln
-17ln + -2lnx = 25ln + -25ln + -1lnx

Combine like terms: 25ln + -25ln = 0
-17ln + -2lnx = 0 + -1lnx
-17ln + -2lnx = -1lnx

Add 'lnx' to each side of the equation.
-17ln + -2lnx + lnx = -1lnx + lnx

Combine like terms: -2lnx + lnx = -1lnx
-17ln + -1lnx = -1lnx + lnx

Combine like terms: -1lnx + lnx = 0
-17ln + -1lnx = 0

Factor out the Greatest Common Factor (GCF), '-1ln'.
-1ln(17 + 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 '(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.
