Simplifying ln(2x + 1) = ln(x + 7) + ln(2) Reorder the terms: ln(1 + 2x) = ln(x + 7) + ln(2) (1 * ln + 2x * ln) = ln(x + 7) + ln(2) (1ln + 2lnx) = ln(x + 7) + ln(2) Reorder the terms: 1ln + 2lnx = ln(7 + x) + ln(2) 1ln + 2lnx = (7 * ln + x * ln) + ln(2) 1ln + 2lnx = (7ln + lnx) + ln(2) Reorder the terms for easier multiplication: 1ln + 2lnx = 7ln + lnx + 2ln Reorder the terms: 1ln + 2lnx = 7ln + 2ln + lnx Combine like terms: 7ln + 2ln = 9ln 1ln + 2lnx = 9ln + lnx Solving 1ln + 2lnx = 9ln + lnx Solving for variable 'l'. Move all terms containing l to the left, all other terms to the right. Add '-9ln' to each side of the equation. 1ln + -9ln + 2lnx = 9ln + -9ln + lnx Combine like terms: 1ln + -9ln = -8ln -8ln + 2lnx = 9ln + -9ln + lnx Combine like terms: 9ln + -9ln = 0 -8ln + 2lnx = 0 + lnx -8ln + 2lnx = lnx Add '-1lnx' to each side of the equation. -8ln + 2lnx + -1lnx = lnx + -1lnx Combine like terms: 2lnx + -1lnx = 1lnx -8ln + 1lnx = lnx + -1lnx Combine like terms: lnx + -1lnx = 0 -8ln + 1lnx = 0 Factor out the Greatest Common Factor (GCF), 'ln'. ln(-8 + 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 '(-8 + x)' equal to zero and attempt to solve: Simplifying -8 + x = 0 Solving -8 + x = 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 + x = 0 + 8 Combine like terms: -8 + 8 = 0 0 + x = 0 + 8 x = 0 + 8 Combine like terms: 0 + 8 = 8 x = 8 Add '-1x' to each side of the equation. x + -1x = 8 + -1x Combine like terms: x + -1x = 0 0 = 8 + -1x Simplifying 0 = 8 + -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.
