Simplifying ln(x + -4) + ln(x + 3) = ln(x + -13) Reorder the terms: ln(-4 + x) + ln(x + 3) = ln(x + -13) (-4 * ln + x * ln) + ln(x + 3) = ln(x + -13) (-4ln + lnx) + ln(x + 3) = ln(x + -13) Reorder the terms: -4ln + lnx + ln(3 + x) = ln(x + -13) -4ln + lnx + (3 * ln + x * ln) = ln(x + -13) -4ln + lnx + (3ln + lnx) = ln(x + -13) Reorder the terms: -4ln + 3ln + lnx + lnx = ln(x + -13) Combine like terms: -4ln + 3ln = -1ln -1ln + lnx + lnx = ln(x + -13) Combine like terms: lnx + lnx = 2lnx -1ln + 2lnx = ln(x + -13) Reorder the terms: -1ln + 2lnx = ln(-13 + x) -1ln + 2lnx = (-13 * ln + x * ln) -1ln + 2lnx = (-13ln + lnx) Solving -1ln + 2lnx = -13ln + lnx Solving for variable 'l'. Move all terms containing l to the left, all other terms to the right. Add '13ln' to each side of the equation. -1ln + 13ln + 2lnx = -13ln + 13ln + lnx Combine like terms: -1ln + 13ln = 12ln 12ln + 2lnx = -13ln + 13ln + lnx Combine like terms: -13ln + 13ln = 0 12ln + 2lnx = 0 + lnx 12ln + 2lnx = lnx Add '-1lnx' to each side of the equation. 12ln + 2lnx + -1lnx = lnx + -1lnx Combine like terms: 2lnx + -1lnx = 1lnx 12ln + 1lnx = lnx + -1lnx Combine like terms: lnx + -1lnx = 0 12ln + 1lnx = 0 Factor out the Greatest Common Factor (GCF), 'ln'. ln(12 + 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 '(12 + x)' equal to zero and attempt to solve: Simplifying 12 + x = 0 Solving 12 + x = 0 Move all terms containing l to the left, all other terms to the right. Add '-12' to each side of the equation. 12 + -12 + x = 0 + -12 Combine like terms: 12 + -12 = 0 0 + x = 0 + -12 x = 0 + -12 Combine like terms: 0 + -12 = -12 x = -12 Add '-1x' to each side of the equation. x + -1x = -12 + -1x Combine like terms: x + -1x = 0 0 = -12 + -1x Simplifying 0 = -12 + -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.
