Simplifying ln(6x) = ln(21 + -1x) Remove parenthesis around (6x) ln * 6x = ln(21 + -1x) Reorder the terms for easier multiplication: 6ln * x = ln(21 + -1x) Multiply ln * x 6lnx = ln(21 + -1x) 6lnx = (21 * ln + -1x * ln) 6lnx = (21ln + -1lnx) Solving 6lnx = 21ln + -1lnx Solving for variable 'l'. Move all terms containing l to the left, all other terms to the right. Add '-21ln' to each side of the equation. -21ln + 6lnx = 21ln + -21ln + -1lnx Combine like terms: 21ln + -21ln = 0 -21ln + 6lnx = 0 + -1lnx -21ln + 6lnx = -1lnx Add 'lnx' to each side of the equation. -21ln + 6lnx + lnx = -1lnx + lnx Combine like terms: 6lnx + lnx = 7lnx -21ln + 7lnx = -1lnx + lnx Combine like terms: -1lnx + lnx = 0 -21ln + 7lnx = 0 Factor out the Greatest Common Factor (GCF), '7ln'. 7ln(-3 + x) = 0 Ignore the factor 7.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.
