Simplifying ln(x + 3) + ln(x) = ln(x + 8) Reorder the terms: ln(3 + x) + ln(x) = ln(x + 8) (3 * ln + x * ln) + ln(x) = ln(x + 8) (3ln + lnx) + ln(x) = ln(x + 8) Multiply ln * x 3ln + lnx + lnx = ln(x + 8) Combine like terms: lnx + lnx = 2lnx 3ln + 2lnx = ln(x + 8) Reorder the terms: 3ln + 2lnx = ln(8 + x) 3ln + 2lnx = (8 * ln + x * ln) 3ln + 2lnx = (8ln + lnx) Solving 3ln + 2lnx = 8ln + lnx Solving for variable 'l'. Move all terms containing l to the left, all other terms to the right. Add '-8ln' to each side of the equation. 3ln + -8ln + 2lnx = 8ln + -8ln + lnx Combine like terms: 3ln + -8ln = -5ln -5ln + 2lnx = 8ln + -8ln + lnx Combine like terms: 8ln + -8ln = 0 -5ln + 2lnx = 0 + lnx -5ln + 2lnx = lnx Add '-1lnx' to each side of the equation. -5ln + 2lnx + -1lnx = lnx + -1lnx Combine like terms: 2lnx + -1lnx = 1lnx -5ln + 1lnx = lnx + -1lnx Combine like terms: lnx + -1lnx = 0 -5ln + 1lnx = 0 Factor out the Greatest Common Factor (GCF), 'ln'. ln(-5 + x) = 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 '(-5 + x)' equal to zero and attempt to solve: Simplifying -5 + x = 0 Solving -5 + x = 0 Move all terms containing l to the left, all other terms to the right. Add '5' to each side of the equation. -5 + 5 + x = 0 + 5 Combine like terms: -5 + 5 = 0 0 + x = 0 + 5 x = 0 + 5 Combine like terms: 0 + 5 = 5 x = 5 Add '-1x' to each side of the equation. x + -1x = 5 + -1x Combine like terms: x + -1x = 0 0 = 5 + -1x Simplifying 0 = 5 + -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.
