Simplifying 2ln(x + 1) = ln(4x + 25) Reorder the terms: 2ln(1 + x) = ln(4x + 25) (1 * 2ln + x * 2ln) = ln(4x + 25) (2ln + 2lnx) = ln(4x + 25) Reorder the terms: 2ln + 2lnx = ln(25 + 4x) 2ln + 2lnx = (25 * ln + 4x * ln) 2ln + 2lnx = (25ln + 4lnx) Solving 2ln + 2lnx = 25ln + 4lnx Solving for variable 'l'. Move all terms containing l to the left, all other terms to the right. Add '-25ln' to each side of the equation. 2ln + -25ln + 2lnx = 25ln + -25ln + 4lnx Combine like terms: 2ln + -25ln = -23ln -23ln + 2lnx = 25ln + -25ln + 4lnx Combine like terms: 25ln + -25ln = 0 -23ln + 2lnx = 0 + 4lnx -23ln + 2lnx = 4lnx Add '-4lnx' to each side of the equation. -23ln + 2lnx + -4lnx = 4lnx + -4lnx Combine like terms: 2lnx + -4lnx = -2lnx -23ln + -2lnx = 4lnx + -4lnx Combine like terms: 4lnx + -4lnx = 0 -23ln + -2lnx = 0 Factor out the Greatest Common Factor (GCF), '-1ln'. -1ln(23 + 2x) = 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 '(23 + 2x)' equal to zero and attempt to solve: Simplifying 23 + 2x = 0 Solving 23 + 2x = 0 Move all terms containing l to the left, all other terms to the right. Add '-23' to each side of the equation. 23 + -23 + 2x = 0 + -23 Combine like terms: 23 + -23 = 0 0 + 2x = 0 + -23 2x = 0 + -23 Combine like terms: 0 + -23 = -23 2x = -23 Add '-2x' to each side of the equation. 2x + -2x = -23 + -2x Combine like terms: 2x + -2x = 0 0 = -23 + -2x Simplifying 0 = -23 + -2x 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.
