Simplifying ln(x) + -1ln(3) = ln(15) Multiply ln * x lnx + -1ln(3) = ln(15) Reorder the terms for easier multiplication: lnx + -1 * 3ln = ln(15) Multiply -1 * 3 lnx + -3ln = ln(15) Reorder the terms: -3ln + lnx = ln(15) Reorder the terms for easier multiplication: -3ln + lnx = 15ln Solving -3ln + lnx = 15ln Solving for variable 'l'. Move all terms containing l to the left, all other terms to the right. Add '-15ln' to each side of the equation. -3ln + -15ln + lnx = 15ln + -15ln Combine like terms: -3ln + -15ln = -18ln -18ln + lnx = 15ln + -15ln Combine like terms: 15ln + -15ln = 0 -18ln + lnx = 0 Factor out the Greatest Common Factor (GCF), 'ln'. ln(-18 + x) = 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 '(-18 + x)' equal to zero and attempt to solve: Simplifying -18 + x = 0 Solving -18 + x = 0 Move all terms containing l to the left, all other terms to the right. Add '18' to each side of the equation. -18 + 18 + x = 0 + 18 Combine like terms: -18 + 18 = 0 0 + x = 0 + 18 x = 0 + 18 Combine like terms: 0 + 18 = 18 x = 18 Add '-1x' to each side of the equation. x + -1x = 18 + -1x Combine like terms: x + -1x = 0 0 = 18 + -1x Simplifying 0 = 18 + -1x 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.
