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

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

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

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

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

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

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

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

Solving
2lnx = 4

Solving for variable 'l'.

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