Simplifying ln(x2 + -9) = (12 + -4x) Reorder the terms: ln(-9 + x2) = (12 + -4x) (-9 * ln + x2 * ln) = (12 + -4x) (-9ln + lnx2) = (12 + -4x) Remove parenthesis around (12 + -4x) -9ln + lnx2 = 12 + -4x Solving -9ln + lnx2 = 12 + -4x Solving for variable 'l'. Move all terms containing l to the left, all other terms to the right. Reorder the terms: -12 + -9ln + lnx2 + 4x = 12 + -4x + -12 + 4x Reorder the terms: -12 + -9ln + lnx2 + 4x = 12 + -12 + -4x + 4x Combine like terms: 12 + -12 = 0 -12 + -9ln + lnx2 + 4x = 0 + -4x + 4x -12 + -9ln + lnx2 + 4x = -4x + 4x Combine like terms: -4x + 4x = 0 -12 + -9ln + lnx2 + 4x = 0 The solution to this equation could not be determined.
