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

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

Simplifying
ln(x + 3) + -1ln(x + -4) = 3

Reorder the terms:
ln(3 + x) + -1ln(x + -4) = 3
(3 * ln + x * ln) + -1ln(x + -4) = 3
(3ln + lnx) + -1ln(x + -4) = 3

Reorder the terms:
3ln + lnx + -1ln(-4 + x) = 3
3ln + lnx + (-4 * -1ln + x * -1ln) = 3
3ln + lnx + (4ln + -1lnx) = 3

Reorder the terms:
3ln + 4ln + lnx + -1lnx = 3

Combine like terms: 3ln + 4ln = 7ln
7ln + lnx + -1lnx = 3

Combine like terms: lnx + -1lnx = 0
7ln + 0 = 3
7ln = 3

Solving
7ln = 3
