Simplifying (ln(x + 4)) + (ln(x + -4)) = 0 Reorder the terms: (ln(4 + x)) + (ln(x + -4)) = 0 ((4 * ln + x * ln)) + (ln(x + -4)) = 0 ((4ln + lnx)) + (ln(x + -4)) = 0 (4ln + lnx) + (ln(x + -4)) = 0 Remove parenthesis around (4ln + lnx) 4ln + lnx + (ln(x + -4)) = 0 Reorder the terms: 4ln + lnx + (ln(-4 + x)) = 0 4ln + lnx + ((-4 * ln + x * ln)) = 0 4ln + lnx + ((-4ln + lnx)) = 0 4ln + lnx + (-4ln + lnx) = 0 Remove parenthesis around (-4ln + lnx) 4ln + lnx + -4ln + lnx = 0 Reorder the terms: 4ln + -4ln + lnx + lnx = 0 Combine like terms: 4ln + -4ln = 0 0 + lnx + lnx = 0 lnx + lnx = 0 Combine like terms: lnx + lnx = 2lnx 2lnx = 0 Solving 2lnx = 0 Solving for variable 'l'. Move all terms containing l to the left, all other terms to the right. Divide each side by '2'. lnx = 0 Simplifying lnx = 0 The solution to this equation could not be determined.
