Simplifying ln(80) + -1ln(2x) = 0 Reorder the terms for easier multiplication: 80ln + -1ln(2x) = 0 Remove parenthesis around (2x) 80ln + -1ln * 2x = 0 Reorder the terms for easier multiplication: 80ln + -1 * 2ln * x = 0 Multiply -1 * 2 80ln + -2ln * x = 0 Multiply ln * x 80ln + -2lnx = 0 Solving 80ln + -2lnx = 0 Solving for variable 'l'. Move all terms containing l to the left, all other terms to the right. Factor out the Greatest Common Factor (GCF), '2ln'. 2ln(40 + -1x) = 0 Ignore the factor 2.Subproblem 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 '(40 + -1x)' equal to zero and attempt to solve: Simplifying 40 + -1x = 0 Solving 40 + -1x = 0 Move all terms containing l to the left, all other terms to the right. Add '-40' to each side of the equation. 40 + -40 + -1x = 0 + -40 Combine like terms: 40 + -40 = 0 0 + -1x = 0 + -40 -1x = 0 + -40 Combine like terms: 0 + -40 = -40 -1x = -40 Add 'x' to each side of the equation. -1x + x = -40 + x Combine like terms: -1x + x = 0 0 = -40 + x Simplifying 0 = -40 + 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.
