Simplifying ln(x) + ln(x + 6) = ln(7) Multiply ln * x lnx + ln(x + 6) = ln(7) Reorder the terms: lnx + ln(6 + x) = ln(7) lnx + (6 * ln + x * ln) = ln(7) lnx + (6ln + lnx) = ln(7) Reorder the terms: 6ln + lnx + lnx = ln(7) Combine like terms: lnx + lnx = 2lnx 6ln + 2lnx = ln(7) Reorder the terms for easier multiplication: 6ln + 2lnx = 7ln Solving 6ln + 2lnx = 7ln Solving for variable 'l'. Move all terms containing l to the left, all other terms to the right. Add '-7ln' to each side of the equation. 6ln + -7ln + 2lnx = 7ln + -7ln Combine like terms: 6ln + -7ln = -1ln -1ln + 2lnx = 7ln + -7ln Combine like terms: 7ln + -7ln = 0 -1ln + 2lnx = 0 Factor out the Greatest Common Factor (GCF), 'ln'. ln(-1 + 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 '(-1 + 2x)' equal to zero and attempt to solve: Simplifying -1 + 2x = 0 Solving -1 + 2x = 0 Move all terms containing l to the left, all other terms to the right. Add '1' to each side of the equation. -1 + 1 + 2x = 0 + 1 Combine like terms: -1 + 1 = 0 0 + 2x = 0 + 1 2x = 0 + 1 Combine like terms: 0 + 1 = 1 2x = 1 Add '-2x' to each side of the equation. 2x + -2x = 1 + -2x Combine like terms: 2x + -2x = 0 0 = 1 + -2x Simplifying 0 = 1 + -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.
