Simplifying ln(x + 9) + ln(x + -4) = 2lnx Reorder the terms: ln(9 + x) + ln(x + -4) = 2lnx (9 * ln + x * ln) + ln(x + -4) = 2lnx (9ln + lnx) + ln(x + -4) = 2lnx Reorder the terms: 9ln + lnx + ln(-4 + x) = 2lnx 9ln + lnx + (-4 * ln + x * ln) = 2lnx 9ln + lnx + (-4ln + lnx) = 2lnx Reorder the terms: 9ln + -4ln + lnx + lnx = 2lnx Combine like terms: 9ln + -4ln = 5ln 5ln + lnx + lnx = 2lnx Combine like terms: lnx + lnx = 2lnx 5ln + 2lnx = 2lnx Add '-2lnx' to each side of the equation. 5ln + 2lnx + -2lnx = 2lnx + -2lnx Combine like terms: 2lnx + -2lnx = 0 5ln + 0 = 2lnx + -2lnx 5ln = 2lnx + -2lnx Combine like terms: 2lnx + -2lnx = 0 5ln = 0 Solving 5ln = 0 Solving for variable 'l'. Move all terms containing l to the left, all other terms to the right. Divide each side by '5'. ln = 0 Simplifying ln = 0 The solution to this equation could not be determined.
