Simplifying ln(9 + x) = ln(12) (9 * ln + x * ln) = ln(12) (9ln + lnx) = ln(12) Reorder the terms for easier multiplication: 9ln + lnx = 12ln Solving 9ln + lnx = 12ln Solving for variable 'l'. Move all terms containing l to the left, all other terms to the right. Add '-12ln' to each side of the equation. 9ln + -12ln + lnx = 12ln + -12ln Combine like terms: 9ln + -12ln = -3ln -3ln + lnx = 12ln + -12ln Combine like terms: 12ln + -12ln = 0 -3ln + lnx = 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.
