Simplifying ln(2) + ln(x + 3) = ln(20) Reorder the terms for easier multiplication: 2ln + ln(x + 3) = ln(20) Reorder the terms: 2ln + ln(3 + x) = ln(20) 2ln + (3 * ln + x * ln) = ln(20) 2ln + (3ln + lnx) = ln(20) Combine like terms: 2ln + 3ln = 5ln 5ln + lnx = ln(20) Reorder the terms for easier multiplication: 5ln + lnx = 20ln Solving 5ln + lnx = 20ln Solving for variable 'l'. Move all terms containing l to the left, all other terms to the right. Add '-20ln' to each side of the equation. 5ln + -20ln + lnx = 20ln + -20ln Combine like terms: 5ln + -20ln = -15ln -15ln + lnx = 20ln + -20ln Combine like terms: 20ln + -20ln = 0 -15ln + lnx = 0 Factor out the Greatest Common Factor (GCF), 'ln'. ln(-15 + 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 '(-15 + x)' equal to zero and attempt to solve: Simplifying -15 + x = 0 Solving -15 + x = 0 Move all terms containing l to the left, all other terms to the right. Add '15' to each side of the equation. -15 + 15 + x = 0 + 15 Combine like terms: -15 + 15 = 0 0 + x = 0 + 15 x = 0 + 15 Combine like terms: 0 + 15 = 15 x = 15 Add '-1x' to each side of the equation. x + -1x = 15 + -1x Combine like terms: x + -1x = 0 0 = 15 + -1x Simplifying 0 = 15 + -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.
