Simplifying Ln(x + 1) + ln(x + 2) = 9 Reorder the terms: nL(1 + x) + ln(x + 2) = 9 (1 * nL + x * nL) + ln(x + 2) = 9 (1nL + nxL) + ln(x + 2) = 9 Reorder the terms: 1nL + nxL + ln(2 + x) = 9 1nL + nxL + (2 * ln + x * ln) = 9 1nL + nxL + (2ln + lnx) = 9 Reorder the terms: 2ln + lnx + 1nL + nxL = 9 Solving 2ln + lnx + 1nL + nxL = 9 Solving for variable 'l'. Move all terms containing l to the left, all other terms to the right. Add '-1nL' to each side of the equation. 2ln + lnx + 1nL + -1nL + nxL = 9 + -1nL Combine like terms: 1nL + -1nL = 0 2ln + lnx + 0 + nxL = 9 + -1nL 2ln + lnx + nxL = 9 + -1nL Add '-1nxL' to each side of the equation. 2ln + lnx + nxL + -1nxL = 9 + -1nL + -1nxL Combine like terms: nxL + -1nxL = 0 2ln + lnx + 0 = 9 + -1nL + -1nxL 2ln + lnx = 9 + -1nL + -1nxL Reorder the terms: -9 + 2ln + lnx + nL + nxL = 9 + -1nL + -1nxL + -9 + nL + nxL Reorder the terms: -9 + 2ln + lnx + nL + nxL = 9 + -9 + -1nL + nL + -1nxL + nxL Combine like terms: 9 + -9 = 0 -9 + 2ln + lnx + nL + nxL = 0 + -1nL + nL + -1nxL + nxL -9 + 2ln + lnx + nL + nxL = -1nL + nL + -1nxL + nxL Combine like terms: -1nL + nL = 0 -9 + 2ln + lnx + nL + nxL = 0 + -1nxL + nxL -9 + 2ln + lnx + nL + nxL = -1nxL + nxL Combine like terms: -1nxL + nxL = 0 -9 + 2ln + lnx + nL + nxL = 0 The solution to this equation could not be determined.
