Simplifying ln(5x + -4) = ln(x + -4) Reorder the terms: ln(-4 + 5x) = ln(x + -4) (-4 * ln + 5x * ln) = ln(x + -4) (-4ln + 5lnx) = ln(x + -4) Reorder the terms: -4ln + 5lnx = ln(-4 + x) -4ln + 5lnx = (-4 * ln + x * ln) -4ln + 5lnx = (-4ln + lnx) Add '4ln' to each side of the equation. -4ln + 4ln + 5lnx = -4ln + 4ln + lnx Combine like terms: -4ln + 4ln = 0 0 + 5lnx = -4ln + 4ln + lnx 5lnx = -4ln + 4ln + lnx Combine like terms: -4ln + 4ln = 0 5lnx = 0 + lnx 5lnx = lnx Solving 5lnx = lnx Solving for variable 'l'. Move all terms containing l to the left, all other terms to the right. Add '-1lnx' to each side of the equation. 5lnx + -1lnx = lnx + -1lnx Combine like terms: 5lnx + -1lnx = 4lnx 4lnx = lnx + -1lnx Combine like terms: lnx + -1lnx = 0 4lnx = 0 Divide each side by '4'. lnx = 0 Simplifying lnx = 0 The solution to this equation could not be determined.
