Simplifying 8ln(x + -10) + -4 = 20 Reorder the terms: 8ln(-10 + x) + -4 = 20 (-10 * 8ln + x * 8ln) + -4 = 20 (-80ln + 8lnx) + -4 = 20 Reorder the terms: -4 + -80ln + 8lnx = 20 Solving -4 + -80ln + 8lnx = 20 Solving for variable 'l'. Move all terms containing l to the left, all other terms to the right. Add '4' to each side of the equation. -4 + -80ln + 4 + 8lnx = 20 + 4 Reorder the terms: -4 + 4 + -80ln + 8lnx = 20 + 4 Combine like terms: -4 + 4 = 0 0 + -80ln + 8lnx = 20 + 4 -80ln + 8lnx = 20 + 4 Combine like terms: 20 + 4 = 24 -80ln + 8lnx = 24 Reorder the terms: -24 + -80ln + 8lnx = 24 + -24 Combine like terms: 24 + -24 = 0 -24 + -80ln + 8lnx = 0 Factor out the Greatest Common Factor (GCF), '8'. 8(-3 + -10ln + lnx) = 0 Ignore the factor 8.Subproblem 1
Set the factor '(-3 + -10ln + lnx)' equal to zero and attempt to solve: Simplifying -3 + -10ln + lnx = 0 Solving -3 + -10ln + lnx = 0 Move all terms containing l to the left, all other terms to the right. Add '3' to each side of the equation. -3 + -10ln + 3 + lnx = 0 + 3 Reorder the terms: -3 + 3 + -10ln + lnx = 0 + 3 Combine like terms: -3 + 3 = 0 0 + -10ln + lnx = 0 + 3 -10ln + lnx = 0 + 3 Combine like terms: 0 + 3 = 3 -10ln + lnx = 3 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.
