ln(x+5)-ln(x-2)=4

Solution for ln(x+5)-ln(x-2)=4 equation:

Simplifying
ln(x + 5) + -1ln(x + -2) = 4

Reorder the terms:
ln(5 + x) + -1ln(x + -2) = 4
(5 * ln + x * ln) + -1ln(x + -2) = 4
(5ln + lnx) + -1ln(x + -2) = 4

Reorder the terms:
5ln + lnx + -1ln(-2 + x) = 4
5ln + lnx + (-2 * -1ln + x * -1ln) = 4
5ln + lnx + (2ln + -1lnx) = 4

Reorder the terms:
5ln + 2ln + lnx + -1lnx = 4

Combine like terms: 5ln + 2ln = 7ln
7ln + lnx + -1lnx = 4

Combine like terms: lnx + -1lnx = 0
7ln + 0 = 4
7ln = 4

Solving
7ln = 4
