Simplifying ln(7x + 2) = ln(2x + -8) Reorder the terms: ln(2 + 7x) = ln(2x + -8) (2 * ln + 7x * ln) = ln(2x + -8) (2ln + 7lnx) = ln(2x + -8) Reorder the terms: 2ln + 7lnx = ln(-8 + 2x) 2ln + 7lnx = (-8 * ln + 2x * ln) 2ln + 7lnx = (-8ln + 2lnx) Solving 2ln + 7lnx = -8ln + 2lnx Solving for variable 'l'. Move all terms containing l to the left, all other terms to the right. Add '8ln' to each side of the equation. 2ln + 8ln + 7lnx = -8ln + 8ln + 2lnx Combine like terms: 2ln + 8ln = 10ln 10ln + 7lnx = -8ln + 8ln + 2lnx Combine like terms: -8ln + 8ln = 0 10ln + 7lnx = 0 + 2lnx 10ln + 7lnx = 2lnx Add '-2lnx' to each side of the equation. 10ln + 7lnx + -2lnx = 2lnx + -2lnx Combine like terms: 7lnx + -2lnx = 5lnx 10ln + 5lnx = 2lnx + -2lnx Combine like terms: 2lnx + -2lnx = 0 10ln + 5lnx = 0 Factor out the Greatest Common Factor (GCF), '5ln'. 5ln(2 + x) = 0 Ignore the factor 5.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 '(2 + x)' equal to zero and attempt to solve: Simplifying 2 + x = 0 Solving 2 + x = 0 Move all terms containing l to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + -2 + x = 0 + -2 Combine like terms: 2 + -2 = 0 0 + x = 0 + -2 x = 0 + -2 Combine like terms: 0 + -2 = -2 x = -2 Add '-1x' to each side of the equation. x + -1x = -2 + -1x Combine like terms: x + -1x = 0 0 = -2 + -1x Simplifying 0 = -2 + -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.
