Simplifying 3ln(x + -5) + 1 = 7 Reorder the terms: 3ln(-5 + x) + 1 = 7 (-5 * 3ln + x * 3ln) + 1 = 7 (-15ln + 3lnx) + 1 = 7 Reorder the terms: 1 + -15ln + 3lnx = 7 Solving 1 + -15ln + 3lnx = 7 Solving for variable 'l'. Move all terms containing l to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -15ln + -1 + 3lnx = 7 + -1 Reorder the terms: 1 + -1 + -15ln + 3lnx = 7 + -1 Combine like terms: 1 + -1 = 0 0 + -15ln + 3lnx = 7 + -1 -15ln + 3lnx = 7 + -1 Combine like terms: 7 + -1 = 6 -15ln + 3lnx = 6 Reorder the terms: -6 + -15ln + 3lnx = 6 + -6 Combine like terms: 6 + -6 = 0 -6 + -15ln + 3lnx = 0 Factor out the Greatest Common Factor (GCF), '3'. 3(-2 + -5ln + lnx) = 0 Ignore the factor 3.Subproblem 1
Set the factor '(-2 + -5ln + lnx)' equal to zero and attempt to solve: Simplifying -2 + -5ln + lnx = 0 Solving -2 + -5ln + lnx = 0 Move all terms containing l to the left, all other terms to the right. Add '2' to each side of the equation. -2 + -5ln + 2 + lnx = 0 + 2 Reorder the terms: -2 + 2 + -5ln + lnx = 0 + 2 Combine like terms: -2 + 2 = 0 0 + -5ln + lnx = 0 + 2 -5ln + lnx = 0 + 2 Combine like terms: 0 + 2 = 2 -5ln + lnx = 2 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.
