Simplifying ln(x2 + 15) = ln(7x + 3) Reorder the terms: ln(15 + x2) = ln(7x + 3) (15 * ln + x2 * ln) = ln(7x + 3) (15ln + lnx2) = ln(7x + 3) Reorder the terms: 15ln + lnx2 = ln(3 + 7x) 15ln + lnx2 = (3 * ln + 7x * ln) 15ln + lnx2 = (3ln + 7lnx) Solving 15ln + lnx2 = 3ln + 7lnx Solving for variable 'l'. Move all terms containing l to the left, all other terms to the right. Add '-3ln' to each side of the equation. 15ln + -3ln + lnx2 = 3ln + -3ln + 7lnx Combine like terms: 15ln + -3ln = 12ln 12ln + lnx2 = 3ln + -3ln + 7lnx Combine like terms: 3ln + -3ln = 0 12ln + lnx2 = 0 + 7lnx 12ln + lnx2 = 7lnx Add '-7lnx' to each side of the equation. 12ln + -7lnx + lnx2 = 7lnx + -7lnx Combine like terms: 7lnx + -7lnx = 0 12ln + -7lnx + lnx2 = 0 Factor out the Greatest Common Factor (GCF), 'ln'. ln(12 + -7x + x2) = 0 Factor a trinomial. ln((3 + -1x)(4 + -1x)) = 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 '(3 + -1x)' equal to zero and attempt to solve: Simplifying 3 + -1x = 0 Solving 3 + -1x = 0 Move all terms containing l to the left, all other terms to the right. Add '-3' to each side of the equation. 3 + -3 + -1x = 0 + -3 Combine like terms: 3 + -3 = 0 0 + -1x = 0 + -3 -1x = 0 + -3 Combine like terms: 0 + -3 = -3 -1x = -3 Add 'x' to each side of the equation. -1x + x = -3 + x Combine like terms: -1x + x = 0 0 = -3 + x Simplifying 0 = -3 + x The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.Subproblem 3
Set the factor '(4 + -1x)' equal to zero and attempt to solve: Simplifying 4 + -1x = 0 Solving 4 + -1x = 0 Move all terms containing l to the left, all other terms to the right. Add '-4' to each side of the equation. 4 + -4 + -1x = 0 + -4 Combine like terms: 4 + -4 = 0 0 + -1x = 0 + -4 -1x = 0 + -4 Combine like terms: 0 + -4 = -4 -1x = -4 Add 'x' to each side of the equation. -1x + x = -4 + x Combine like terms: -1x + x = 0 0 = -4 + x Simplifying 0 = -4 + x 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.
