Simplifying
Ln(x) + ln(x + -8) = ln(20)

Multiply nL * x
nxL + ln(x + -8) = ln(20)

Reorder the terms:
nxL + ln(-8 + x) = ln(20)
nxL + (-8 * ln + x * ln) = ln(20)
nxL + (-8ln + lnx) = ln(20)

Reorder the terms:
-8ln + lnx + nxL = ln(20)

Reorder the terms for easier multiplication:
-8ln + lnx + nxL = 20ln

Solving
-8ln + lnx + nxL = 20ln

Solving for variable 'l'.

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

Add '-20ln' to each side of the equation.
-8ln + lnx + -20ln + nxL = 20ln + -20ln

Reorder the terms:
-8ln + -20ln + lnx + nxL = 20ln + -20ln

Combine like terms: -8ln + -20ln = -28ln
-28ln + lnx + nxL = 20ln + -20ln

Combine like terms: 20ln + -20ln = 0
-28ln + lnx + nxL = 0

Add '-1nxL' to each side of the equation.
-28ln + lnx + nxL + -1nxL = 0 + -1nxL

Combine like terms: nxL + -1nxL = 0
-28ln + lnx + 0 = 0 + -1nxL
-28ln + lnx = 0 + -1nxL
Remove the zero:
-28ln + lnx = -1nxL

Combine like terms: -1nxL + nxL = 0
-28ln + lnx + nxL = 0

Factor out the Greatest Common Factor (GCF), 'n'.
n(-28l + lx + 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 '(-28l + lx + xL)' equal to zero and attempt to solve: Simplifying -28l + lx + xL = 0 Solving -28l + lx + xL = 0 Move all terms containing l to the left, all other terms to the right. Add '-1xL' to each side of the equation. -28l + lx + xL + -1xL = 0 + -1xL Combine like terms: xL + -1xL = 0 -28l + lx + 0 = 0 + -1xL -28l + lx = 0 + -1xL Remove the zero: -28l + lx = -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.
