Simplifying ln(x) + -1ln(x + -4) = ln(18) Multiply ln * x lnx + -1ln(x + -4) = ln(18) Reorder the terms: lnx + -1ln(-4 + x) = ln(18) lnx + (-4 * -1ln + x * -1ln) = ln(18) lnx + (4ln + -1lnx) = ln(18) Reorder the terms: 4ln + lnx + -1lnx = ln(18) Combine like terms: lnx + -1lnx = 0 4ln + 0 = ln(18) 4ln = ln(18) Reorder the terms for easier multiplication: 4ln = 18ln Solving 4ln = 18ln Solving for variable 'l'. Move all terms containing l to the left, all other terms to the right. Add '-18ln' to each side of the equation. 4ln + -18ln = 18ln + -18ln Combine like terms: 4ln + -18ln = -14ln -14ln = 18ln + -18ln Combine like terms: 18ln + -18ln = 0 -14ln = 0 Divide each side by '-14'. ln = 0 Simplifying ln = 0 The solution to this equation could not be determined.
