Simplifying ln((2x) + -1) = ln(15) Reorder the terms: ln(-1 + (2x)) = ln(15) (-1 * ln + (2x) * ln) = ln(15) (-1ln + 2lnx) = ln(15) Reorder the terms for easier multiplication: -1ln + 2lnx = 15ln Solving -1ln + 2lnx = 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. -1ln + -15ln + 2lnx = 15ln + -15ln Combine like terms: -1ln + -15ln = -16ln -16ln + 2lnx = 15ln + -15ln Combine like terms: 15ln + -15ln = 0 -16ln + 2lnx = 0 Factor out the Greatest Common Factor (GCF), '2ln'. 2ln(-8 + x) = 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 '(-8 + x)' equal to zero and attempt to solve: Simplifying -8 + x = 0 Solving -8 + x = 0 Move all terms containing l to the left, all other terms to the right. Add '8' to each side of the equation. -8 + 8 + x = 0 + 8 Combine like terms: -8 + 8 = 0 0 + x = 0 + 8 x = 0 + 8 Combine like terms: 0 + 8 = 8 x = 8 Add '-1x' to each side of the equation. x + -1x = 8 + -1x Combine like terms: x + -1x = 0 0 = 8 + -1x Simplifying 0 = 8 + -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.
