Simplifying -1ln(2x) + -1ln(x + 4) = -1ln(x) + -1ln(x + 20) Remove parenthesis around (2x) -1ln * 2x + -1ln(x + 4) = -1ln(x) + -1ln(x + 20) Reorder the terms for easier multiplication: -1 * 2ln * x + -1ln(x + 4) = -1ln(x) + -1ln(x + 20) Multiply -1 * 2 -2ln * x + -1ln(x + 4) = -1ln(x) + -1ln(x + 20) Multiply ln * x -2lnx + -1ln(x + 4) = -1ln(x) + -1ln(x + 20) Reorder the terms: -2lnx + -1ln(4 + x) = -1ln(x) + -1ln(x + 20) -2lnx + (4 * -1ln + x * -1ln) = -1ln(x) + -1ln(x + 20) -2lnx + (-4ln + -1lnx) = -1ln(x) + -1ln(x + 20) Reorder the terms: -4ln + -2lnx + -1lnx = -1ln(x) + -1ln(x + 20) Combine like terms: -2lnx + -1lnx = -3lnx -4ln + -3lnx = -1ln(x) + -1ln(x + 20) Multiply ln * x -4ln + -3lnx = -1lnx + -1ln(x + 20) Reorder the terms: -4ln + -3lnx = -1lnx + -1ln(20 + x) -4ln + -3lnx = -1lnx + (20 * -1ln + x * -1ln) -4ln + -3lnx = -1lnx + (-20ln + -1lnx) Reorder the terms: -4ln + -3lnx = -20ln + -1lnx + -1lnx Combine like terms: -1lnx + -1lnx = -2lnx -4ln + -3lnx = -20ln + -2lnx Solving -4ln + -3lnx = -20ln + -2lnx 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. -4ln + 20ln + -3lnx = -20ln + 20ln + -2lnx Combine like terms: -4ln + 20ln = 16ln 16ln + -3lnx = -20ln + 20ln + -2lnx Combine like terms: -20ln + 20ln = 0 16ln + -3lnx = 0 + -2lnx 16ln + -3lnx = -2lnx Add '2lnx' to each side of the equation. 16ln + -3lnx + 2lnx = -2lnx + 2lnx Combine like terms: -3lnx + 2lnx = -1lnx 16ln + -1lnx = -2lnx + 2lnx Combine like terms: -2lnx + 2lnx = 0 16ln + -1lnx = 0 Factor out the Greatest Common Factor (GCF), 'ln'. ln(16 + -1x) = 0Subproblem 1
Set the factor 'ln' equal to zero and attempt to solve: Simplifying ln = 0 Solving ln = 0 Move all terms containing l to the left, all other terms to the right. Simplifying ln = 0 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 '(16 + -1x)' equal to zero and attempt to solve: Simplifying 16 + -1x = 0 Solving 16 + -1x = 0 Move all terms containing l to the left, all other terms to the right. Add '-16' to each side of the equation. 16 + -16 + -1x = 0 + -16 Combine like terms: 16 + -16 = 0 0 + -1x = 0 + -16 -1x = 0 + -16 Combine like terms: 0 + -16 = -16 -1x = -16 Add 'x' to each side of the equation. -1x + x = -16 + x Combine like terms: -1x + x = 0 0 = -16 + x Simplifying 0 = -16 + x 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.
