Simplifying ln(X + 2) + ln(x + -2) = ln(21) Reorder the terms: ln(2 + X) + ln(x + -2) = ln(21) (2 * ln + X * ln) + ln(x + -2) = ln(21) (2ln + lnX) + ln(x + -2) = ln(21) Reorder the terms: 2ln + lnX + ln(-2 + x) = ln(21) 2ln + lnX + (-2 * ln + x * ln) = ln(21) 2ln + lnX + (-2ln + lnx) = ln(21) Reorder the terms: 2ln + -2ln + lnX + lnx = ln(21) Combine like terms: 2ln + -2ln = 0 0 + lnX + lnx = ln(21) lnX + lnx = ln(21) Reorder the terms for easier multiplication: lnX + lnx = 21ln Solving lnX + lnx = 21ln Solving for variable 'l'. Move all terms containing l to the left, all other terms to the right. Add '-21ln' to each side of the equation. lnX + -21ln + lnx = 21ln + -21ln Reorder the terms: -21ln + lnX + lnx = 21ln + -21ln Combine like terms: 21ln + -21ln = 0 -21ln + lnX + lnx = 0 Factor out the Greatest Common Factor (GCF), 'ln'. ln(-21 + X + x) = 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 '(-21 + X + x)' equal to zero and attempt to solve: Simplifying -21 + X + x = 0 Solving -21 + X + x = 0 Move all terms containing l to the left, all other terms to the right. Add '21' to each side of the equation. -21 + X + 21 + x = 0 + 21 Reorder the terms: -21 + 21 + X + x = 0 + 21 Combine like terms: -21 + 21 = 0 0 + X + x = 0 + 21 X + x = 0 + 21 Combine like terms: 0 + 21 = 21 X + x = 21 Add '-1X' to each side of the equation. X + -1X + x = 21 + -1X Combine like terms: X + -1X = 0 0 + x = 21 + -1X x = 21 + -1X Add '-1x' to each side of the equation. x + -1x = 21 + -1X + -1x Combine like terms: x + -1x = 0 0 = 21 + -1X + -1x Simplifying 0 = 21 + -1X + -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.
