Simplifying 2ln(x) = 21ln(2) Multiply ln * x 2lnx = 21ln(2) Reorder the terms for easier multiplication: 2lnx = 21 * 2ln Multiply 21 * 2 2lnx = 42ln Solving 2lnx = 42ln Solving for variable 'l'. Move all terms containing l to the left, all other terms to the right. Add '-42ln' to each side of the equation. -42ln + 2lnx = 42ln + -42ln Combine like terms: 42ln + -42ln = 0 -42ln + 2lnx = 0 Factor out the Greatest Common Factor (GCF), '2ln'. 2ln(-21 + x) = 0 Ignore the factor 2.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 '(-21 + x)' equal to zero and attempt to solve: Simplifying -21 + x = 0 Solving -21 + x = 0 Move all terms containing l to the left, all other terms to the right. Add '21' to each side of the equation. -21 + 21 + x = 0 + 21 Combine like terms: -21 + 21 = 0 0 + x = 0 + 21 x = 0 + 21 Combine like terms: 0 + 21 = 21 x = 21 Add '-1x' to each side of the equation. x + -1x = 21 + -1x Combine like terms: x + -1x = 0 0 = 21 + -1x Simplifying 0 = 21 + -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.
