Simplifying ln(4x + 15) + ln(3) = 2ln(x) Reorder the terms: ln(15 + 4x) + ln(3) = 2ln(x) (15 * ln + 4x * ln) + ln(3) = 2ln(x) (15ln + 4lnx) + ln(3) = 2ln(x) Reorder the terms for easier multiplication: 15ln + 4lnx + 3ln = 2ln(x) Reorder the terms: 15ln + 3ln + 4lnx = 2ln(x) Combine like terms: 15ln + 3ln = 18ln 18ln + 4lnx = 2ln(x) Multiply ln * x 18ln + 4lnx = 2lnx Solving 18ln + 4lnx = 2lnx Solving for variable 'l'. Move all terms containing l to the left, all other terms to the right. Add '-2lnx' to each side of the equation. 18ln + 4lnx + -2lnx = 2lnx + -2lnx Combine like terms: 4lnx + -2lnx = 2lnx 18ln + 2lnx = 2lnx + -2lnx Combine like terms: 2lnx + -2lnx = 0 18ln + 2lnx = 0 Factor out the Greatest Common Factor (GCF), '2ln'. 2ln(9 + 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 '(9 + x)' equal to zero and attempt to solve: Simplifying 9 + x = 0 Solving 9 + x = 0 Move all terms containing l to the left, all other terms to the right. Add '-9' to each side of the equation. 9 + -9 + x = 0 + -9 Combine like terms: 9 + -9 = 0 0 + x = 0 + -9 x = 0 + -9 Combine like terms: 0 + -9 = -9 x = -9 Add '-1x' to each side of the equation. x + -1x = -9 + -1x Combine like terms: x + -1x = 0 0 = -9 + -1x Simplifying 0 = -9 + -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.
