Simplifying ln(2x + 3) + ln(x + 1) = ln(10) Reorder the terms: ln(3 + 2x) + ln(x + 1) = ln(10) (3 * ln + 2x * ln) + ln(x + 1) = ln(10) (3ln + 2lnx) + ln(x + 1) = ln(10) Reorder the terms: 3ln + 2lnx + ln(1 + x) = ln(10) 3ln + 2lnx + (1 * ln + x * ln) = ln(10) 3ln + 2lnx + (1ln + lnx) = ln(10) Reorder the terms: 3ln + 1ln + 2lnx + lnx = ln(10) Combine like terms: 3ln + 1ln = 4ln 4ln + 2lnx + lnx = ln(10) Combine like terms: 2lnx + lnx = 3lnx 4ln + 3lnx = ln(10) Reorder the terms for easier multiplication: 4ln + 3lnx = 10ln Solving 4ln + 3lnx = 10ln Solving for variable 'l'. Move all terms containing l to the left, all other terms to the right. Add '-10ln' to each side of the equation. 4ln + -10ln + 3lnx = 10ln + -10ln Combine like terms: 4ln + -10ln = -6ln -6ln + 3lnx = 10ln + -10ln Combine like terms: 10ln + -10ln = 0 -6ln + 3lnx = 0 Factor out the Greatest Common Factor (GCF), '3ln'. 3ln(-2 + x) = 0 Ignore the factor 3.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.
