Simplifying ln(x + -3) + ln(x + 3) = ln(16) Reorder the terms: ln(-3 + x) + ln(x + 3) = ln(16) (-3 * ln + x * ln) + ln(x + 3) = ln(16) (-3ln + lnx) + ln(x + 3) = ln(16) Reorder the terms: -3ln + lnx + ln(3 + x) = ln(16) -3ln + lnx + (3 * ln + x * ln) = ln(16) -3ln + lnx + (3ln + lnx) = ln(16) Reorder the terms: -3ln + 3ln + lnx + lnx = ln(16) Combine like terms: -3ln + 3ln = 0 0 + lnx + lnx = ln(16) lnx + lnx = ln(16) Combine like terms: lnx + lnx = 2lnx 2lnx = ln(16) Reorder the terms for easier multiplication: 2lnx = 16ln Solving 2lnx = 16ln Solving for variable 'l'. Move all terms containing l to the left, all other terms to the right. Add '-16ln' to each side of the equation. -16ln + 2lnx = 16ln + -16ln Combine like terms: 16ln + -16ln = 0 -16ln + 2lnx = 0 Factor out the Greatest Common Factor (GCF), '2ln'. 2ln(-8 + 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 '(-8 + x)' equal to zero and attempt to solve: Simplifying -8 + x = 0 Solving -8 + x = 0 Move all terms containing l to the left, all other terms to the right. Add '8' to each side of the equation. -8 + 8 + x = 0 + 8 Combine like terms: -8 + 8 = 0 0 + x = 0 + 8 x = 0 + 8 Combine like terms: 0 + 8 = 8 x = 8 Add '-1x' to each side of the equation. x + -1x = 8 + -1x Combine like terms: x + -1x = 0 0 = 8 + -1x Simplifying 0 = 8 + -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.
