Simplifying
Ln(2x + 5) + Ln(x + -4) + -2lnx = 0

Reorder the terms:
nL(5 + 2x) + Ln(x + -4) + -2lnx = 0
(5 * nL + 2x * nL) + Ln(x + -4) + -2lnx = 0
(5nL + 2nxL) + Ln(x + -4) + -2lnx = 0

Reorder the terms:
5nL + 2nxL + nL(-4 + x) + -2lnx = 0
5nL + 2nxL + (-4 * nL + x * nL) + -2lnx = 0
5nL + 2nxL + (-4nL + nxL) + -2lnx = 0

Reorder the terms:
-2lnx + 5nL + -4nL + 2nxL + nxL = 0

Combine like terms: 5nL + -4nL = 1nL
-2lnx + 1nL + 2nxL + nxL = 0

Combine like terms: 2nxL + nxL = 3nxL
-2lnx + 1nL + 3nxL = 0

Solving
-2lnx + 1nL + 3nxL = 0

Solving for variable 'l'.

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

Add '-1nL' to each side of the equation.
-2lnx + 1nL + -1nL + 3nxL = 0 + -1nL

Combine like terms: 1nL + -1nL = 0
-2lnx + 0 + 3nxL = 0 + -1nL
-2lnx + 3nxL = 0 + -1nL
Remove the zero:
-2lnx + 3nxL = -1nL

Add '-3nxL' to each side of the equation.
-2lnx + 3nxL + -3nxL = -1nL + -3nxL

Combine like terms: 3nxL + -3nxL = 0
-2lnx + 0 = -1nL + -3nxL
-2lnx = -1nL + -3nxL

Divide each side by '-2nx'.
l = 0.5x-1L + 1.5L

Simplifying
l = 0.5x-1L + 1.5L

Reorder the terms:
l = 1.5L + 0.5x-1L
