Simplifying ln(2) + ln(x) = ln(7) + ln(2x + -4) Reorder the terms for easier multiplication: 2ln + ln(x) = ln(7) + ln(2x + -4) Multiply ln * x 2ln + lnx = ln(7) + ln(2x + -4) Reorder the terms for easier multiplication: 2ln + lnx = 7ln + ln(2x + -4) Reorder the terms: 2ln + lnx = 7ln + ln(-4 + 2x) 2ln + lnx = 7ln + (-4 * ln + 2x * ln) 2ln + lnx = 7ln + (-4ln + 2lnx) Combine like terms: 7ln + -4ln = 3ln 2ln + lnx = 3ln + 2lnx Solving 2ln + lnx = 3ln + 2lnx 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. 2ln + -3ln + lnx = 3ln + -3ln + 2lnx Combine like terms: 2ln + -3ln = -1ln -1ln + lnx = 3ln + -3ln + 2lnx Combine like terms: 3ln + -3ln = 0 -1ln + lnx = 0 + 2lnx -1ln + lnx = 2lnx Add '-2lnx' to each side of the equation. -1ln + lnx + -2lnx = 2lnx + -2lnx Combine like terms: lnx + -2lnx = -1lnx -1ln + -1lnx = 2lnx + -2lnx Combine like terms: 2lnx + -2lnx = 0 -1ln + -1lnx = 0 Factor out the Greatest Common Factor (GCF), '-1ln'. -1ln(1 + x) = 0 Ignore the factor -1.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.
