Solution for ln(5x-3)=ln(4x+8) equation: 


Simplifying
ln(5x + -3) = ln(4x + 8)

Reorder the terms:
ln(-3 + 5x) = ln(4x + 8)
(-3 * ln + 5x * ln) = ln(4x + 8)
(-3ln + 5lnx) = ln(4x + 8)

Reorder the terms:
-3ln + 5lnx = ln(8 + 4x)
-3ln + 5lnx = (8 * ln + 4x * ln)
-3ln + 5lnx = (8ln + 4lnx)

Solving
-3ln + 5lnx = 8ln + 4lnx

Solving for variable 'l'.

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

Add '-8ln' to each side of the equation.
-3ln + -8ln + 5lnx = 8ln + -8ln + 4lnx

Combine like terms: -3ln + -8ln = -11ln
-11ln + 5lnx = 8ln + -8ln + 4lnx

Combine like terms: 8ln + -8ln = 0
-11ln + 5lnx = 0 + 4lnx
-11ln + 5lnx = 4lnx

Add '-4lnx' to each side of the equation.
-11ln + 5lnx + -4lnx = 4lnx + -4lnx

Combine like terms: 5lnx + -4lnx = 1lnx
-11ln + 1lnx = 4lnx + -4lnx

Combine like terms: 4lnx + -4lnx = 0
-11ln + 1lnx = 0
