Simplifying 4ln(x + 4) + -8 = 0 Reorder the terms: 4ln(4 + x) + -8 = 0 (4 * 4ln + x * 4ln) + -8 = 0 (16ln + 4lnx) + -8 = 0 Reorder the terms: -8 + 16ln + 4lnx = 0 Solving -8 + 16ln + 4lnx = 0 Solving for variable 'l'. Move all terms containing l to the left, all other terms to the right. Add '8' to each side of the equation. -8 + 16ln + 8 + 4lnx = 0 + 8 Reorder the terms: -8 + 8 + 16ln + 4lnx = 0 + 8 Combine like terms: -8 + 8 = 0 0 + 16ln + 4lnx = 0 + 8 16ln + 4lnx = 0 + 8 Combine like terms: 0 + 8 = 8 16ln + 4lnx = 8 Reorder the terms: -8 + 16ln + 4lnx = 8 + -8 Combine like terms: 8 + -8 = 0 -8 + 16ln + 4lnx = 0 Factor out the Greatest Common Factor (GCF), '4'. 4(-2 + 4ln + lnx) = 0 Ignore the factor 4.Subproblem 1
Set the factor '(-2 + 4ln + lnx)' equal to zero and attempt to solve: Simplifying -2 + 4ln + lnx = 0 Solving -2 + 4ln + lnx = 0 Move all terms containing l to the left, all other terms to the right. Add '2' to each side of the equation. -2 + 4ln + 2 + lnx = 0 + 2 Reorder the terms: -2 + 2 + 4ln + lnx = 0 + 2 Combine like terms: -2 + 2 = 0 0 + 4ln + lnx = 0 + 2 4ln + lnx = 0 + 2 Combine like terms: 0 + 2 = 2 4ln + lnx = 2 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.
