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


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

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

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

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

Add '-1lnx' to each side of the equation.
-4 + 3ln + lnx + -1lnx = -5ln + lnx + -1lnx

Combine like terms: lnx + -1lnx = 0
-4 + 3ln + 0 = -5ln + lnx + -1lnx
-4 + 3ln = -5ln + lnx + -1lnx

Combine like terms: lnx + -1lnx = 0
-4 + 3ln = -5ln + 0
-4 + 3ln = -5ln

Solving
-4 + 3ln = -5ln

Solving for variable 'l'.

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