Simplifying lnx + ln(x + 7) = ln * 18 Reorder the terms: lnx + ln(7 + x) = ln * 18 lnx + (7 * ln + x * ln) = ln * 18 lnx + (7ln + lnx) = ln * 18 Reorder the terms: 7ln + lnx + lnx = ln * 18 Combine like terms: lnx + lnx = 2lnx 7ln + 2lnx = ln * 18 Reorder the terms for easier multiplication: 7ln + 2lnx = 18ln Solving 7ln + 2lnx = 18ln Solving for variable 'l'. Move all terms containing l to the left, all other terms to the right. Add '-18ln' to each side of the equation. 7ln + -18ln + 2lnx = 18ln + -18ln Combine like terms: 7ln + -18ln = -11ln -11ln + 2lnx = 18ln + -18ln Combine like terms: 18ln + -18ln = 0 -11ln + 2lnx = 0 Factor out the Greatest Common Factor (GCF), 'ln'. ln(-11 + 2x) = 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 '(-11 + 2x)' equal to zero and attempt to solve: Simplifying -11 + 2x = 0 Solving -11 + 2x = 0 Move all terms containing l to the left, all other terms to the right. Add '11' to each side of the equation. -11 + 11 + 2x = 0 + 11 Combine like terms: -11 + 11 = 0 0 + 2x = 0 + 11 2x = 0 + 11 Combine like terms: 0 + 11 = 11 2x = 11 Add '-2x' to each side of the equation. 2x + -2x = 11 + -2x Combine like terms: 2x + -2x = 0 0 = 11 + -2x Simplifying 0 = 11 + -2x 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.
