Solution for In(x-6)+In(x+1)=In(x-15) equation:


Simplifying
In(x + -6) + In(x + 1) = In(x + -15)

Reorder the terms:
nI(-6 + x) + In(x + 1) = In(x + -15)
(-6 * nI + x * nI) + In(x + 1) = In(x + -15)
(-6nI + nxI) + In(x + 1) = In(x + -15)

Reorder the terms:
-6nI + nxI + nI(1 + x) = In(x + -15)
-6nI + nxI + (1 * nI + x * nI) = In(x + -15)
-6nI + nxI + (1nI + nxI) = In(x + -15)

Reorder the terms:
-6nI + 1nI + nxI + nxI = In(x + -15)

Combine like terms: -6nI + 1nI = -5nI
-5nI + nxI + nxI = In(x + -15)

-5nI + 2nxI = nI(-15 + x)
-5nI + 2nxI = (-15 * nI + x * nI)
-5nI + 2nxI = (-15nI + nxI)

Solving
-5nI + 2nxI = -15nI + nxI

Solving for variable 'n'.

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

Add '15nI' to each side of the equation.
-5nI + 15nI + 2nxI = -15nI + 15nI + nxI

Combine like terms: -5nI + 15nI = 10nI
10nI + 2nxI = -15nI + 15nI + nxI

Combine like terms: -15nI + 15nI = 0
10nI + 2nxI = 0 + nxI
10nI + 2nxI = nxI

Add '-1nxI' to each side of the equation.
10nI + 2nxI + -1nxI = nxI + -1nxI

Combine like terms: 2nxI + -1nxI = 1nxI
10nI + 1nxI = nxI + -1nxI

Combine like terms: nxI + -1nxI = 0
10nI + 1nxI = 0

Factor out the Greatest Common Factor (GCF), 'nI'.
nI(10 + x) = 0

Subproblem 1

Set the factor 'nI' equal to zero and attempt to solve: Simplifying nI = 0 Solving nI = 0 Move all terms containing n to the left, all other terms to the right. Simplifying nI = 0 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.
