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