Simplifying ln(x) + ln(x + -3) = ln(3x) Multiply ln * x lnx + ln(x + -3) = ln(3x) Reorder the terms: lnx + ln(-3 + x) = ln(3x) lnx + (-3 * ln + x * ln) = ln(3x) lnx + (-3ln + lnx) = ln(3x) Reorder the terms: -3ln + lnx + lnx = ln(3x) Combine like terms: lnx + lnx = 2lnx -3ln + 2lnx = ln(3x) Remove parenthesis around (3x) -3ln + 2lnx = ln * 3x Reorder the terms for easier multiplication: -3ln + 2lnx = 3ln * x Multiply ln * x -3ln + 2lnx = 3lnx Solving -3ln + 2lnx = 3lnx Solving for variable 'l'. Move all terms containing l to the left, all other terms to the right. Add '-3lnx' to each side of the equation. -3ln + 2lnx + -3lnx = 3lnx + -3lnx Combine like terms: 2lnx + -3lnx = -1lnx -3ln + -1lnx = 3lnx + -3lnx Combine like terms: 3lnx + -3lnx = 0 -3ln + -1lnx = 0 Factor out the Greatest Common Factor (GCF), '-1ln'. -1ln(3 + 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 '(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.
