Simplifying ln(3x + -7) + -1ln(5x + 1) = 0 Reorder the terms: ln(-7 + 3x) + -1ln(5x + 1) = 0 (-7 * ln + 3x * ln) + -1ln(5x + 1) = 0 (-7ln + 3lnx) + -1ln(5x + 1) = 0 Reorder the terms: -7ln + 3lnx + -1ln(1 + 5x) = 0 -7ln + 3lnx + (1 * -1ln + 5x * -1ln) = 0 -7ln + 3lnx + (-1ln + -5lnx) = 0 Reorder the terms: -7ln + -1ln + 3lnx + -5lnx = 0 Combine like terms: -7ln + -1ln = -8ln -8ln + 3lnx + -5lnx = 0 Combine like terms: 3lnx + -5lnx = -2lnx -8ln + -2lnx = 0 Solving -8ln + -2lnx = 0 Solving for variable 'l'. Move all terms containing l to the left, all other terms to the right. Factor out the Greatest Common Factor (GCF), '-2ln'. -2ln(4 + 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 '(4 + x)' equal to zero and attempt to solve: Simplifying 4 + x = 0 Solving 4 + x = 0 Move all terms containing l to the left, all other terms to the right. Add '-4' to each side of the equation. 4 + -4 + x = 0 + -4 Combine like terms: 4 + -4 = 0 0 + x = 0 + -4 x = 0 + -4 Combine like terms: 0 + -4 = -4 x = -4 Add '-1x' to each side of the equation. x + -1x = -4 + -1x Combine like terms: x + -1x = 0 0 = -4 + -1x Simplifying 0 = -4 + -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.
