Simplifying ln(x + -2) = ln(7x) Reorder the terms: ln(-2 + x) = ln(7x) (-2 * ln + x * ln) = ln(7x) (-2ln + lnx) = ln(7x) Remove parenthesis around (7x) -2ln + lnx = ln * 7x Reorder the terms for easier multiplication: -2ln + lnx = 7ln * x Multiply ln * x -2ln + lnx = 7lnx Solving -2ln + lnx = 7lnx Solving for variable 'l'. Move all terms containing l to the left, all other terms to the right. Add '-7lnx' to each side of the equation. -2ln + lnx + -7lnx = 7lnx + -7lnx Combine like terms: lnx + -7lnx = -6lnx -2ln + -6lnx = 7lnx + -7lnx Combine like terms: 7lnx + -7lnx = 0 -2ln + -6lnx = 0 Factor out the Greatest Common Factor (GCF), '-2ln'. -2ln(1 + 3x) = 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 '(1 + 3x)' equal to zero and attempt to solve: Simplifying 1 + 3x = 0 Solving 1 + 3x = 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 + 3x = 0 + -1 Combine like terms: 1 + -1 = 0 0 + 3x = 0 + -1 3x = 0 + -1 Combine like terms: 0 + -1 = -1 3x = -1 Add '-3x' to each side of the equation. 3x + -3x = -1 + -3x Combine like terms: 3x + -3x = 0 0 = -1 + -3x Simplifying 0 = -1 + -3x 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.
