ln(x+1)+ln(x-1)=8

Solution for ln(x+1)+ln(x-1)=8 equation:

Simplifying
ln(x + 1) + ln(x + -1) = 8

Reorder the terms:
ln(1 + x) + ln(x + -1) = 8
(1 * ln + x * ln) + ln(x + -1) = 8
(1ln + lnx) + ln(x + -1) = 8

Reorder the terms:
1ln + lnx + ln(-1 + x) = 8
1ln + lnx + (-1 * ln + x * ln) = 8
1ln + lnx + (-1ln + lnx) = 8

Reorder the terms:
1ln + -1ln + lnx + lnx = 8

Combine like terms: 1ln + -1ln = 0
0 + lnx + lnx = 8
lnx + lnx = 8

Combine like terms: lnx + lnx = 2lnx
2lnx = 8

Solving
2lnx = 8

Solving for variable 'l'.

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

Divide each side by '2nx'.
l = 4n-1x-1

Simplifying
l = 4n-1x-1
