-4ln + -1lnx + 5nL + nxL = 4

Solving
-4ln + -1lnx + 5nL + nxL = 4

Solving for variable 'l'.

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

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

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

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

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

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

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

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

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

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