Simplifying ln(8x + 7) + -1ln * x = ln * 9 Reorder the terms: ln(7 + 8x) + -1ln * x = ln * 9 (7 * ln + 8x * ln) + -1ln * x = ln * 9 (7ln + 8lnx) + -1ln * x = ln * 9 Multiply ln * x 7ln + 8lnx + -1lnx = ln * 9 Combine like terms: 8lnx + -1lnx = 7lnx 7ln + 7lnx = ln * 9 Reorder the terms for easier multiplication: 7ln + 7lnx = 9ln Solving 7ln + 7lnx = 9ln Solving for variable 'l'. Move all terms containing l to the left, all other terms to the right. Add '-9ln' to each side of the equation. 7ln + -9ln + 7lnx = 9ln + -9ln Combine like terms: 7ln + -9ln = -2ln -2ln + 7lnx = 9ln + -9ln Combine like terms: 9ln + -9ln = 0 -2ln + 7lnx = 0 Factor out the Greatest Common Factor (GCF), 'ln'. ln(-2 + 7x) = 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 '(-2 + 7x)' equal to zero and attempt to solve: Simplifying -2 + 7x = 0 Solving -2 + 7x = 0 Move all terms containing l to the left, all other terms to the right. Add '2' to each side of the equation. -2 + 2 + 7x = 0 + 2 Combine like terms: -2 + 2 = 0 0 + 7x = 0 + 2 7x = 0 + 2 Combine like terms: 0 + 2 = 2 7x = 2 Add '-7x' to each side of the equation. 7x + -7x = 2 + -7x Combine like terms: 7x + -7x = 0 0 = 2 + -7x Simplifying 0 = 2 + -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.
