Simplifying ln(x + 5) + ln(x + -1) = ln(x + 1) Reorder the terms: ln(5 + x) + ln(x + -1) = ln(x + 1) (5 * ln + x * ln) + ln(x + -1) = ln(x + 1) (5ln + lnx) + ln(x + -1) = ln(x + 1) Reorder the terms: 5ln + lnx + ln(-1 + x) = ln(x + 1) 5ln + lnx + (-1 * ln + x * ln) = ln(x + 1) 5ln + lnx + (-1ln + lnx) = ln(x + 1) Reorder the terms: 5ln + -1ln + lnx + lnx = ln(x + 1) Combine like terms: 5ln + -1ln = 4ln 4ln + lnx + lnx = ln(x + 1) Combine like terms: lnx + lnx = 2lnx 4ln + 2lnx = ln(x + 1) Reorder the terms: 4ln + 2lnx = ln(1 + x) 4ln + 2lnx = (1 * ln + x * ln) 4ln + 2lnx = (1ln + lnx) Solving 4ln + 2lnx = 1ln + lnx Solving for variable 'l'. Move all terms containing l to the left, all other terms to the right. Add '-1ln' to each side of the equation. 4ln + -1ln + 2lnx = 1ln + -1ln + lnx Combine like terms: 4ln + -1ln = 3ln 3ln + 2lnx = 1ln + -1ln + lnx Combine like terms: 1ln + -1ln = 0 3ln + 2lnx = 0 + lnx 3ln + 2lnx = lnx Add '-1lnx' to each side of the equation. 3ln + 2lnx + -1lnx = lnx + -1lnx Combine like terms: 2lnx + -1lnx = 1lnx 3ln + 1lnx = lnx + -1lnx Combine like terms: lnx + -1lnx = 0 3ln + 1lnx = 0 Factor out the Greatest Common Factor (GCF), 'ln'. ln(3 + 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 '(3 + x)' equal to zero and attempt to solve: Simplifying 3 + x = 0 Solving 3 + x = 0 Move all terms containing l to the left, all other terms to the right. Add '-3' to each side of the equation. 3 + -3 + x = 0 + -3 Combine like terms: 3 + -3 = 0 0 + x = 0 + -3 x = 0 + -3 Combine like terms: 0 + -3 = -3 x = -3 Add '-1x' to each side of the equation. x + -1x = -3 + -1x Combine like terms: x + -1x = 0 0 = -3 + -1x Simplifying 0 = -3 + -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.
