Simplifying ln(x + 8) + ln(7) = 4 Reorder the terms: ln(8 + x) + ln(7) = 4 (8 * ln + x * ln) + ln(7) = 4 (8ln + lnx) + ln(7) = 4 Reorder the terms for easier multiplication: 8ln + lnx + 7ln = 4 Reorder the terms: 8ln + 7ln + lnx = 4 Combine like terms: 8ln + 7ln = 15ln 15ln + lnx = 4 Solving 15ln + lnx = 4 Solving for variable 'l'. Move all terms containing l to the left, all other terms to the right. Reorder the terms: -4 + 15ln + lnx = 4 + -4 Combine like terms: 4 + -4 = 0 -4 + 15ln + lnx = 0 The solution to this equation could not be determined.
