Simplifying ln(x + -5) + ln(x + -7) = 0 Reorder the terms: ln(-5 + x) + ln(x + -7) = 0 (-5 * ln + x * ln) + ln(x + -7) = 0 (-5ln + lnx) + ln(x + -7) = 0 Reorder the terms: -5ln + lnx + ln(-7 + x) = 0 -5ln + lnx + (-7 * ln + x * ln) = 0 -5ln + lnx + (-7ln + lnx) = 0 Reorder the terms: -5ln + -7ln + lnx + lnx = 0 Combine like terms: -5ln + -7ln = -12ln -12ln + lnx + lnx = 0 Combine like terms: lnx + lnx = 2lnx -12ln + 2lnx = 0 Solving -12ln + 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(-6 + 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 '(-6 + x)' equal to zero and attempt to solve: Simplifying -6 + x = 0 Solving -6 + x = 0 Move all terms containing l to the left, all other terms to the right. Add '6' to each side of the equation. -6 + 6 + x = 0 + 6 Combine like terms: -6 + 6 = 0 0 + x = 0 + 6 x = 0 + 6 Combine like terms: 0 + 6 = 6 x = 6 Add '-1x' to each side of the equation. x + -1x = 6 + -1x Combine like terms: x + -1x = 0 0 = 6 + -1x Simplifying 0 = 6 + -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.
