Solution for In(x+2)-In(x-5)=In(x-9) equation:


Simplifying
In(x + 2) + -1In(x + -5) = In(x + -9)

Reorder the terms:
nI(2 + x) + -1In(x + -5) = In(x + -9)
(2 * nI + x * nI) + -1In(x + -5) = In(x + -9)
(2nI + nxI) + -1In(x + -5) = In(x + -9)

Reorder the terms:
2nI + nxI + -1nI(-5 + x) = In(x + -9)
2nI + nxI + (-5 * -1nI + x * -1nI) = In(x + -9)
2nI + nxI + (5nI + -1nxI) = In(x + -9)

Reorder the terms:
2nI + 5nI + nxI + -1nxI = In(x + -9)

Combine like terms: 2nI + 5nI = 7nI
7nI + nxI + -1nxI = In(x + -9)

Combine like terms: nxI + -1nxI = 0
7nI + 0 = In(x + -9)
7nI = In(x + -9)

Reorder the terms:
7nI = nI(-9 + x)
7nI = (-9 * nI + x * nI)
7nI = (-9nI + nxI)

Solving
7nI = -9nI + nxI

Solving for variable 'n'.

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

Add '9nI' to each side of the equation.
7nI + 9nI = -9nI + 9nI + nxI

Combine like terms: 7nI + 9nI = 16nI
16nI = -9nI + 9nI + nxI

Combine like terms: -9nI + 9nI = 0
16nI = 0 + nxI
16nI = nxI

Add '-1nxI' to each side of the equation.
16nI + -1nxI = nxI + -1nxI

Combine like terms: nxI + -1nxI = 0
16nI + -1nxI = 0
