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