Simplifying 2ln(x + -4) = ln(x + 2) + ln(x + 9) Reorder the terms: 2ln(-4 + x) = ln(x + 2) + ln(x + 9) (-4 * 2ln + x * 2ln) = ln(x + 2) + ln(x + 9) (-8ln + 2lnx) = ln(x + 2) + ln(x + 9) Reorder the terms: -8ln + 2lnx = ln(2 + x) + ln(x + 9) -8ln + 2lnx = (2 * ln + x * ln) + ln(x + 9) -8ln + 2lnx = (2ln + lnx) + ln(x + 9) Reorder the terms: -8ln + 2lnx = 2ln + lnx + ln(9 + x) -8ln + 2lnx = 2ln + lnx + (9 * ln + x * ln) -8ln + 2lnx = 2ln + lnx + (9ln + lnx) Reorder the terms: -8ln + 2lnx = 2ln + 9ln + lnx + lnx Combine like terms: 2ln + 9ln = 11ln -8ln + 2lnx = 11ln + lnx + lnx Combine like terms: lnx + lnx = 2lnx -8ln + 2lnx = 11ln + 2lnx Add '-2lnx' to each side of the equation. -8ln + 2lnx + -2lnx = 11ln + 2lnx + -2lnx Combine like terms: 2lnx + -2lnx = 0 -8ln + 0 = 11ln + 2lnx + -2lnx -8ln = 11ln + 2lnx + -2lnx Combine like terms: 2lnx + -2lnx = 0 -8ln = 11ln + 0 -8ln = 11ln Solving -8ln = 11ln Solving for variable 'l'. Move all terms containing l to the left, all other terms to the right. Add '-11ln' to each side of the equation. -8ln + -11ln = 11ln + -11ln Combine like terms: -8ln + -11ln = -19ln -19ln = 11ln + -11ln Combine like terms: 11ln + -11ln = 0 -19ln = 0 Divide each side by '-19'. ln = 0 Simplifying ln = 0 The solution to this equation could not be determined.
