Simplifying ln(3x + -19) = ln(x + 13) Reorder the terms: ln(-19 + 3x) = ln(x + 13) (-19 * ln + 3x * ln) = ln(x + 13) (-19ln + 3lnx) = ln(x + 13) Reorder the terms: -19ln + 3lnx = ln(13 + x) -19ln + 3lnx = (13 * ln + x * ln) -19ln + 3lnx = (13ln + lnx) Solving -19ln + 3lnx = 13ln + lnx Solving for variable 'l'. Move all terms containing l to the left, all other terms to the right. Add '-13ln' to each side of the equation. -19ln + -13ln + 3lnx = 13ln + -13ln + lnx Combine like terms: -19ln + -13ln = -32ln -32ln + 3lnx = 13ln + -13ln + lnx Combine like terms: 13ln + -13ln = 0 -32ln + 3lnx = 0 + lnx -32ln + 3lnx = lnx Add '-1lnx' to each side of the equation. -32ln + 3lnx + -1lnx = lnx + -1lnx Combine like terms: 3lnx + -1lnx = 2lnx -32ln + 2lnx = lnx + -1lnx Combine like terms: lnx + -1lnx = 0 -32ln + 2lnx = 0 Factor out the Greatest Common Factor (GCF), '2ln'. 2ln(-16 + x) = 0 Ignore the factor 2.Subproblem 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 '(-16 + x)' equal to zero and attempt to solve: Simplifying -16 + x = 0 Solving -16 + x = 0 Move all terms containing l to the left, all other terms to the right. Add '16' to each side of the equation. -16 + 16 + x = 0 + 16 Combine like terms: -16 + 16 = 0 0 + x = 0 + 16 x = 0 + 16 Combine like terms: 0 + 16 = 16 x = 16 Add '-1x' to each side of the equation. x + -1x = 16 + -1x Combine like terms: x + -1x = 0 0 = 16 + -1x Simplifying 0 = 16 + -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.
