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.
10ln + -1lnx + 4nL + -8ln + nxL = 8ln + -8ln

Reorder the terms:
10ln + -8ln + -1lnx + 4nL + nxL = 8ln + -8ln

Combine like terms: 10ln + -8ln = 2ln
2ln + -1lnx + 4nL + nxL = 8ln + -8ln

Combine like terms: 8ln + -8ln = 0
2ln + -1lnx + 4nL + nxL = 0

Add '-4nL' to each side of the equation.
2ln + -1lnx + 4nL + -4nL + nxL = 0 + -4nL

2ln + -1lnx + 0 + nxL = 0 + -4nL
2ln + -1lnx + nxL = 0 + -4nL
Remove the zero:
2ln + -1lnx + nxL = -4nL

Add '-1nxL' to each side of the equation.
2ln + -1lnx + nxL + -1nxL = -4nL + -1nxL

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

Reorder the terms:
2ln + -1lnx + 4nL + nxL = -4nL + 4nL + -1nxL + nxL

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

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

Factor out the Greatest Common Factor (GCF), 'n'.
n(2l + -1lx + 4L + xL) = 0

Subproblem 1

Set the factor 'n' equal to zero and attempt to solve: Simplifying n = 0 Solving n = 0 Move all terms containing l to the left, all other terms to the right. Add '-1n' to each side of the equation. n + -1n = 0 + -1n Remove the zero: 0 = -1n Simplifying 0 = -1n The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.

Subproblem 2
