Simplifying ln(9x + 2) + -1lnx = ln(10) Reorder the terms: ln(2 + 9x) + -1lnx = ln(10) (2 * ln + 9x * ln) + -1lnx = ln(10) (2ln + 9lnx) + -1lnx = ln(10) Combine like terms: 9lnx + -1lnx = 8lnx 2ln + 8lnx = ln(10) Reorder the terms for easier multiplication: 2ln + 8lnx = 10ln Solving 2ln + 8lnx = 10ln Solving for variable 'l'. Move all terms containing l to the left, all other terms to the right. Add '-10ln' to each side of the equation. 2ln + -10ln + 8lnx = 10ln + -10ln Combine like terms: 2ln + -10ln = -8ln -8ln + 8lnx = 10ln + -10ln Combine like terms: 10ln + -10ln = 0 -8ln + 8lnx = 0 Factor out the Greatest Common Factor (GCF), '8ln'. 8ln(-1 + x) = 0 Ignore the factor 8.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 '(-1 + x)' equal to zero and attempt to solve: Simplifying -1 + x = 0 Solving -1 + x = 0 Move all terms containing l to the left, all other terms to the right. Add '1' to each side of the equation. -1 + 1 + x = 0 + 1 Combine like terms: -1 + 1 = 0 0 + x = 0 + 1 x = 0 + 1 Combine like terms: 0 + 1 = 1 x = 1 Add '-1x' to each side of the equation. x + -1x = 1 + -1x Combine like terms: x + -1x = 0 0 = 1 + -1x Simplifying 0 = 1 + -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.
