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