ln(x+2)+ln(x-2)=7

Solution for ln(x+2)+ln(x-2)=7 equation:

Simplifying
ln(x + 2) + ln(x + -2) = 7

Reorder the terms:
ln(2 + x) + ln(x + -2) = 7
(2 * ln + x * ln) + ln(x + -2) = 7
(2ln + lnx) + ln(x + -2) = 7

Reorder the terms:
2ln + lnx + ln(-2 + x) = 7
2ln + lnx + (-2 * ln + x * ln) = 7
2ln + lnx + (-2ln + lnx) = 7

Reorder the terms:
2ln + -2ln + lnx + lnx = 7

Combine like terms: 2ln + -2ln = 0
0 + lnx + lnx = 7
lnx + lnx = 7

Combine like terms: lnx + lnx = 2lnx
2lnx = 7

Solving
2lnx = 7

Solving for variable 'l'.

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