Simplifying 2lnx = ln(8 + 7x) 2lnx = (8 * ln + 7x * ln) 2lnx = (8ln + 7lnx) Solving 2lnx = 8ln + 7lnx Solving for variable 'l'. Move all terms containing l to the left, all other terms to the right. Add '-8ln' to each side of the equation. -8ln + 2lnx = 8ln + -8ln + 7lnx Combine like terms: 8ln + -8ln = 0 -8ln + 2lnx = 0 + 7lnx -8ln + 2lnx = 7lnx Add '-7lnx' to each side of the equation. -8ln + 2lnx + -7lnx = 7lnx + -7lnx Combine like terms: 2lnx + -7lnx = -5lnx -8ln + -5lnx = 7lnx + -7lnx Combine like terms: 7lnx + -7lnx = 0 -8ln + -5lnx = 0 Factor out the Greatest Common Factor (GCF), '-1ln'. -1ln(8 + 5x) = 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 '(8 + 5x)' equal to zero and attempt to solve: Simplifying 8 + 5x = 0 Solving 8 + 5x = 0 Move all terms containing l to the left, all other terms to the right. Add '-8' to each side of the equation. 8 + -8 + 5x = 0 + -8 Combine like terms: 8 + -8 = 0 0 + 5x = 0 + -8 5x = 0 + -8 Combine like terms: 0 + -8 = -8 5x = -8 Add '-5x' to each side of the equation. 5x + -5x = -8 + -5x Combine like terms: 5x + -5x = 0 0 = -8 + -5x Simplifying 0 = -8 + -5x 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.
