In(x+1)+In(x-1)=4

Solution for In(x+1)+In(x-1)=4 equation:

Simplifying
In(x + 1) + In(x + -1) = 4

Reorder the terms:
nI(1 + x) + In(x + -1) = 4
(1 * nI + x * nI) + In(x + -1) = 4
(1nI + nxI) + In(x + -1) = 4

Reorder the terms:
1nI + nxI + nI(-1 + x) = 4
1nI + nxI + (-1 * nI + x * nI) = 4
1nI + nxI + (-1nI + nxI) = 4

Reorder the terms:
1nI + -1nI + nxI + nxI = 4

Combine like terms: 1nI + -1nI = 0
0 + nxI + nxI = 4
nxI + nxI = 4

Combine like terms: nxI + nxI = 2nxI
2nxI = 4

Solving
2nxI = 4

Solving for variable 'n'.

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

Divide each side by '2xI'.
n = 2x-1I-1

Simplifying
n = 2x-1I-1
