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