ln(x+4)-ln(x-5)=5

Solution for ln(x+4)-ln(x-5)=5 equation:

Simplifying
ln(x + 4) + -1ln(x + -5) = 5

Reorder the terms:
ln(4 + x) + -1ln(x + -5) = 5
(4 * ln + x * ln) + -1ln(x + -5) = 5
(4ln + lnx) + -1ln(x + -5) = 5

Reorder the terms:
4ln + lnx + -1ln(-5 + x) = 5
4ln + lnx + (-5 * -1ln + x * -1ln) = 5
4ln + lnx + (5ln + -1lnx) = 5

Reorder the terms:
4ln + 5ln + lnx + -1lnx = 5

Combine like terms: 4ln + 5ln = 9ln
9ln + lnx + -1lnx = 5

Combine like terms: lnx + -1lnx = 0
9ln + 0 = 5
9ln = 5

Solving
9ln = 5
