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