ln(x+4)+ln(x-4)=3

Solution for ln(x+4)+ln(x-4)=3 equation:

Simplifying
ln(x + 4) + ln(x + -4) = 3

Reorder the terms:
ln(4 + x) + ln(x + -4) = 3
(4 * ln + x * ln) + ln(x + -4) = 3
(4ln + lnx) + ln(x + -4) = 3

Reorder the terms:
4ln + lnx + ln(-4 + x) = 3
4ln + lnx + (-4 * ln + x * ln) = 3
4ln + lnx + (-4ln + lnx) = 3

Reorder the terms:
4ln + -4ln + lnx + lnx = 3

Combine like terms: 4ln + -4ln = 0
0 + lnx + lnx = 3
lnx + lnx = 3

Combine like terms: lnx + lnx = 2lnx
2lnx = 3

Solving
2lnx = 3

Solving for variable 'l'.

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