Simplifying 2lnx + -1ln(2x + -9) = ln(7x) + -1ln(x + -2) Reorder the terms: 2lnx + -1ln(-9 + 2x) = ln(7x) + -1ln(x + -2) 2lnx + (-9 * -1ln + 2x * -1ln) = ln(7x) + -1ln(x + -2) 2lnx + (9ln + -2lnx) = ln(7x) + -1ln(x + -2) Reorder the terms: 9ln + 2lnx + -2lnx = ln(7x) + -1ln(x + -2) Combine like terms: 2lnx + -2lnx = 0 9ln + 0 = ln(7x) + -1ln(x + -2) 9ln = ln(7x) + -1ln(x + -2) Remove parenthesis around (7x) 9ln = ln * 7x + -1ln(x + -2) Reorder the terms for easier multiplication: 9ln = 7ln * x + -1ln(x + -2) Multiply ln * x 9ln = 7lnx + -1ln(x + -2) Reorder the terms: 9ln = 7lnx + -1ln(-2 + x) 9ln = 7lnx + (-2 * -1ln + x * -1ln) 9ln = 7lnx + (2ln + -1lnx) Reorder the terms: 9ln = 2ln + 7lnx + -1lnx Combine like terms: 7lnx + -1lnx = 6lnx 9ln = 2ln + 6lnx Solving 9ln = 2ln + 6lnx Solving for variable 'l'. Move all terms containing l to the left, all other terms to the right. Add '-2ln' to each side of the equation. 9ln + -2ln = 2ln + -2ln + 6lnx Combine like terms: 9ln + -2ln = 7ln 7ln = 2ln + -2ln + 6lnx Combine like terms: 2ln + -2ln = 0 7ln = 0 + 6lnx 7ln = 6lnx Add '-6lnx' to each side of the equation. 7ln + -6lnx = 6lnx + -6lnx Combine like terms: 6lnx + -6lnx = 0 7ln + -6lnx = 0 Factor out the Greatest Common Factor (GCF), 'ln'. ln(7 + -6x) = 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 '(7 + -6x)' equal to zero and attempt to solve: Simplifying 7 + -6x = 0 Solving 7 + -6x = 0 Move all terms containing l to the left, all other terms to the right. Add '-7' to each side of the equation. 7 + -7 + -6x = 0 + -7 Combine like terms: 7 + -7 = 0 0 + -6x = 0 + -7 -6x = 0 + -7 Combine like terms: 0 + -7 = -7 -6x = -7 Add '6x' to each side of the equation. -6x + 6x = -7 + 6x Combine like terms: -6x + 6x = 0 0 = -7 + 6x Simplifying 0 = -7 + 6x 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.
