Simplifying ln(x + -2) + ln(x + -5) = ln(18) Reorder the terms: ln(-2 + x) + ln(x + -5) = ln(18) (-2 * ln + x * ln) + ln(x + -5) = ln(18) (-2ln + lnx) + ln(x + -5) = ln(18) Reorder the terms: -2ln + lnx + ln(-5 + x) = ln(18) -2ln + lnx + (-5 * ln + x * ln) = ln(18) -2ln + lnx + (-5ln + lnx) = ln(18) Reorder the terms: -2ln + -5ln + lnx + lnx = ln(18) Combine like terms: -2ln + -5ln = -7ln -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 = -25ln -25ln + 2lnx = 18ln + -18ln Combine like terms: 18ln + -18ln = 0 -25ln + 2lnx = 0 Factor out the Greatest Common Factor (GCF), 'ln'. ln(-25 + 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 '(-25 + 2x)' equal to zero and attempt to solve: Simplifying -25 + 2x = 0 Solving -25 + 2x = 0 Move all terms containing l to the left, all other terms to the right. Add '25' to each side of the equation. -25 + 25 + 2x = 0 + 25 Combine like terms: -25 + 25 = 0 0 + 2x = 0 + 25 2x = 0 + 25 Combine like terms: 0 + 25 = 25 2x = 25 Add '-2x' to each side of the equation. 2x + -2x = 25 + -2x Combine like terms: 2x + -2x = 0 0 = 25 + -2x Simplifying 0 = 25 + -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.
