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