Simplifying 2ln(x + -3) = ln(9x) Reorder the terms: 2ln(-3 + x) = ln(9x) (-3 * 2ln + x * 2ln) = ln(9x) (-6ln + 2lnx) = ln(9x) Remove parenthesis around (9x) -6ln + 2lnx = ln * 9x Reorder the terms for easier multiplication: -6ln + 2lnx = 9ln * x Multiply ln * x -6ln + 2lnx = 9lnx Solving -6ln + 2lnx = 9lnx Solving for variable 'l'. Move all terms containing l to the left, all other terms to the right. Add '-9lnx' to each side of the equation. -6ln + 2lnx + -9lnx = 9lnx + -9lnx Combine like terms: 2lnx + -9lnx = -7lnx -6ln + -7lnx = 9lnx + -9lnx Combine like terms: 9lnx + -9lnx = 0 -6ln + -7lnx = 0 Factor out the Greatest Common Factor (GCF), '-1ln'. -1ln(6 + 7x) = 0 Ignore the factor -1.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 + 7x)' equal to zero and attempt to solve: Simplifying 6 + 7x = 0 Solving 6 + 7x = 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 + 7x = 0 + -6 Combine like terms: 6 + -6 = 0 0 + 7x = 0 + -6 7x = 0 + -6 Combine like terms: 0 + -6 = -6 7x = -6 Add '-7x' to each side of the equation. 7x + -7x = -6 + -7x Combine like terms: 7x + -7x = 0 0 = -6 + -7x Simplifying 0 = -6 + -7x 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.
