ln(x+4)-ln(x-4)=4

Solution for ln(x+4)-ln(x-4)=4 equation:

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

Reorder the terms:
ln(4 + x) + -1ln(x + -4) = 4
(4 * ln + x * ln) + -1ln(x + -4) = 4
(4ln + lnx) + -1ln(x + -4) = 4

Reorder the terms:
4ln + lnx + -1ln(-4 + x) = 4
4ln + lnx + (-4 * -1ln + x * -1ln) = 4
4ln + lnx + (4ln + -1lnx) = 4

Reorder the terms:
4ln + 4ln + lnx + -1lnx = 4

Combine like terms: 4ln + 4ln = 8ln
8ln + lnx + -1lnx = 4

Combine like terms: lnx + -1lnx = 0
8ln + 0 = 4
8ln = 4

Solving
8ln = 4
