Simplifying ln(9x + 13) + -1ln * x = ln * 10 Reorder the terms: ln(13 + 9x) + -1ln * x = ln * 10 (13 * ln + 9x * ln) + -1ln * x = ln * 10 (13ln + 9lnx) + -1ln * x = ln * 10 Multiply ln * x 13ln + 9lnx + -1lnx = ln * 10 Combine like terms: 9lnx + -1lnx = 8lnx 13ln + 8lnx = ln * 10 Reorder the terms for easier multiplication: 13ln + 8lnx = 10ln Solving 13ln + 8lnx = 10ln Solving for variable 'l'. Move all terms containing l to the left, all other terms to the right. Add '-10ln' to each side of the equation. 13ln + -10ln + 8lnx = 10ln + -10ln Combine like terms: 13ln + -10ln = 3ln 3ln + 8lnx = 10ln + -10ln Combine like terms: 10ln + -10ln = 0 3ln + 8lnx = 0 Factor out the Greatest Common Factor (GCF), 'ln'. ln(3 + 8x) = 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 + 8x)' equal to zero and attempt to solve: Simplifying 3 + 8x = 0 Solving 3 + 8x = 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 + 8x = 0 + -3 Combine like terms: 3 + -3 = 0 0 + 8x = 0 + -3 8x = 0 + -3 Combine like terms: 0 + -3 = -3 8x = -3 Add '-8x' to each side of the equation. 8x + -8x = -3 + -8x Combine like terms: 8x + -8x = 0 0 = -3 + -8x Simplifying 0 = -3 + -8x 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.
