Simplifying 9 = ln(x + 7) Reorder the terms: 9 = ln(7 + x) 9 = (7 * ln + x * ln) 9 = (7ln + lnx) Solving 9 = 7ln + lnx Solving for variable 'l'. Move all terms containing l to the left, all other terms to the right. Add '-7ln' to each side of the equation. 9 + -7ln = 7ln + -7ln + lnx Combine like terms: 7ln + -7ln = 0 9 + -7ln = 0 + lnx 9 + -7ln = lnx Add '-1lnx' to each side of the equation. 9 + -7ln + -1lnx = lnx + -1lnx Combine like terms: lnx + -1lnx = 0 9 + -7ln + -1lnx = 0 Add '-9' to each side of the equation. 9 + -7ln + -9 + -1lnx = 0 + -9 Reorder the terms: 9 + -9 + -7ln + -1lnx = 0 + -9 Combine like terms: 9 + -9 = 0 0 + -7ln + -1lnx = 0 + -9 -7ln + -1lnx = 0 + -9 Combine like terms: 0 + -9 = -9 -7ln + -1lnx = -9 Reorder the terms: 9 + -7ln + -1lnx = -9 + 9 Combine like terms: -9 + 9 = 0 9 + -7ln + -1lnx = 0 The solution to this equation could not be determined.
