ln(x-5)-ln(x+3)=4

Solution for ln(x-5)-ln(x+3)=4 equation:

Simplifying
ln(x + -5) + -1ln(x + 3) = 4

Reorder the terms:
ln(-5 + x) + -1ln(x + 3) = 4
(-5 * ln + x * ln) + -1ln(x + 3) = 4
(-5ln + lnx) + -1ln(x + 3) = 4

Reorder the terms:
-5ln + lnx + -1ln(3 + x) = 4
-5ln + lnx + (3 * -1ln + x * -1ln) = 4
-5ln + lnx + (-3ln + -1lnx) = 4

Reorder the terms:
-5ln + -3ln + lnx + -1lnx = 4

Combine like terms: -5ln + -3ln = -8ln
-8ln + lnx + -1lnx = 4

Combine like terms: lnx + -1lnx = 0
-8ln + 0 = 4
-8ln = 4

Solving
-8ln = 4
