-7ln + lnx + nxL + -1nxL = -7nL + -1nxL

Combine like terms: nxL + -1nxL = 0
-7ln + lnx + 0 = -7nL + -1nxL
-7ln + lnx = -7nL + -1nxL

Reorder the terms:
-7ln + lnx + 7nL + nxL = -7nL + 7nL + -1nxL + nxL

Combine like terms: -7nL + 7nL = 0
-7ln + lnx + 7nL + nxL = 0 + -1nxL + nxL
-7ln + lnx + 7nL + nxL = -1nxL + nxL

Combine like terms: -1nxL + nxL = 0
-7ln + lnx + 7nL + nxL = 0

Factor out the Greatest Common Factor (GCF), 'n'.
n(-7l + lx + 7L + 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

Set the factor '(-7l + lx + 7L + xL)' equal to zero and attempt to solve: Simplifying -7l + lx + 7L + xL = 0 Reorder the terms: 7L + -7l + lx + xL = 0 Solving 7L + -7l + lx + xL = 0 Move all terms containing l to the left, all other terms to the right. Add '-7L' to each side of the equation. 7L + -7l + lx + -7L + xL = 0 + -7L Reorder the terms: 7L + -7L + -7l + lx + xL = 0 + -7L Combine like terms: 7L + -7L = 0 0 + -7l + lx + xL = 0 + -7L -7l + lx + xL = 0 + -7L Remove the zero: -7l + lx + xL = -7L Add '-1xL' to each side of the equation. -7l + lx + xL + -1xL = -7L + -1xL Combine like terms: xL + -1xL = 0 -7l + lx + 0 = -7L + -1xL -7l + lx = -7L + -1xL The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined. The solution to this equation could not be determined.
