Simplifying 4 = ln(x + -9) Reorder the terms: 4 = ln(-9 + x) 4 = (-9 * ln + x * ln) 4 = (-9ln + lnx) Solving 4 = -9ln + lnx Solving for variable 'l'. Move all terms containing l to the left, all other terms to the right. Add '9ln' to each side of the equation. 4 + 9ln = -9ln + 9ln + lnx Combine like terms: -9ln + 9ln = 0 4 + 9ln = 0 + lnx 4 + 9ln = lnx Add '-1lnx' to each side of the equation. 4 + 9ln + -1lnx = lnx + -1lnx Combine like terms: lnx + -1lnx = 0 4 + 9ln + -1lnx = 0 Add '-4' to each side of the equation. 4 + 9ln + -4 + -1lnx = 0 + -4 Reorder the terms: 4 + -4 + 9ln + -1lnx = 0 + -4 Combine like terms: 4 + -4 = 0 0 + 9ln + -1lnx = 0 + -4 9ln + -1lnx = 0 + -4 Combine like terms: 0 + -4 = -4 9ln + -1lnx = -4 Reorder the terms: 4 + 9ln + -1lnx = -4 + 4 Combine like terms: -4 + 4 = 0 4 + 9ln + -1lnx = 0 The solution to this equation could not be determined.
