(8 * ln + x * ln) + ln(4) = ln(19)
(8ln + lnx) + ln(4) = ln(19)

Reorder the terms for easier multiplication:
8ln + lnx + 4ln = ln(19)

Reorder the terms:
8ln + 4ln + lnx = ln(19)

Combine like terms: 8ln + 4ln = 12ln
12ln + lnx = ln(19)

Reorder the terms for easier multiplication:
12ln + lnx = 19ln

Solving
12ln + lnx = 19ln

Solving for variable 'l'.

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

Add '-19ln' to each side of the equation.
12ln + -19ln + lnx = 19ln + -19ln

Combine like terms: 12ln + -19ln = -7ln
-7ln + lnx = 19ln + -19ln

Combine like terms: 19ln + -19ln = 0
-7ln + lnx = 0
