Simplifying 4ln(x + -4) + ln(x + 1) = 0 Reorder the terms: 4ln(-4 + x) + ln(x + 1) = 0 (-4 * 4ln + x * 4ln) + ln(x + 1) = 0 (-16ln + 4lnx) + ln(x + 1) = 0 Reorder the terms: -16ln + 4lnx + ln(1 + x) = 0 -16ln + 4lnx + (1 * ln + x * ln) = 0 -16ln + 4lnx + (1ln + lnx) = 0 Reorder the terms: -16ln + 1ln + 4lnx + lnx = 0 Combine like terms: -16ln + 1ln = -15ln -15ln + 4lnx + lnx = 0 Combine like terms: 4lnx + lnx = 5lnx -15ln + 5lnx = 0 Solving -15ln + 5lnx = 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), '5ln'. 5ln(-3 + x) = 0 Ignore the factor 5.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 '(-3 + x)' equal to zero and attempt to solve: Simplifying -3 + x = 0 Solving -3 + x = 0 Move all terms containing l to the left, all other terms to the right. Add '3' to each side of the equation. -3 + 3 + x = 0 + 3 Combine like terms: -3 + 3 = 0 0 + x = 0 + 3 x = 0 + 3 Combine like terms: 0 + 3 = 3 x = 3 Add '-1x' to each side of the equation. x + -1x = 3 + -1x Combine like terms: x + -1x = 0 0 = 3 + -1x Simplifying 0 = 3 + -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.
