Simplifying ln(x) + ln(x + -2) = ln(120) Multiply ln * x lnx + ln(x + -2) = ln(120) Reorder the terms: lnx + ln(-2 + x) = ln(120) lnx + (-2 * ln + x * ln) = ln(120) lnx + (-2ln + lnx) = ln(120) Reorder the terms: -2ln + lnx + lnx = ln(120) Combine like terms: lnx + lnx = 2lnx -2ln + 2lnx = ln(120) Reorder the terms for easier multiplication: -2ln + 2lnx = 120ln Solving -2ln + 2lnx = 120ln Solving for variable 'l'. Move all terms containing l to the left, all other terms to the right. Add '-120ln' to each side of the equation. -2ln + -120ln + 2lnx = 120ln + -120ln Combine like terms: -2ln + -120ln = -122ln -122ln + 2lnx = 120ln + -120ln Combine like terms: 120ln + -120ln = 0 -122ln + 2lnx = 0 Factor out the Greatest Common Factor (GCF), '2ln'. 2ln(-61 + 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 '(-61 + x)' equal to zero and attempt to solve: Simplifying -61 + x = 0 Solving -61 + x = 0 Move all terms containing l to the left, all other terms to the right. Add '61' to each side of the equation. -61 + 61 + x = 0 + 61 Combine like terms: -61 + 61 = 0 0 + x = 0 + 61 x = 0 + 61 Combine like terms: 0 + 61 = 61 x = 61 Add '-1x' to each side of the equation. x + -1x = 61 + -1x Combine like terms: x + -1x = 0 0 = 61 + -1x Simplifying 0 = 61 + -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.
