Simplifying ln(x) = ln(x + 7) + -1ln(2) Multiply ln * x lnx = ln(x + 7) + -1ln(2) Reorder the terms: lnx = ln(7 + x) + -1ln(2) lnx = (7 * ln + x * ln) + -1ln(2) lnx = (7ln + lnx) + -1ln(2) Reorder the terms for easier multiplication: lnx = 7ln + lnx + -1 * 2ln Multiply -1 * 2 lnx = 7ln + lnx + -2ln Reorder the terms: lnx = 7ln + -2ln + lnx Combine like terms: 7ln + -2ln = 5ln lnx = 5ln + lnx Add '-1lnx' to each side of the equation. lnx + -1lnx = 5ln + lnx + -1lnx Combine like terms: lnx + -1lnx = 0 0 = 5ln + lnx + -1lnx Combine like terms: lnx + -1lnx = 0 0 = 5ln + 0 0 = 5ln Solving 0 = 5ln Solving for variable 'l'. Move all terms containing l to the left, all other terms to the right. Add '-5ln' to each side of the equation. 0 + -5ln = 5ln + -5ln Remove the zero: -5ln = 5ln + -5ln Combine like terms: 5ln + -5ln = 0 -5ln = 0 Divide each side by '-5'. ln = 0 Simplifying ln = 0 The solution to this equation could not be determined.
