Simplifying ln(x + 4) = ln(x + 2x + 4) Reorder the terms: ln(4 + x) = ln(x + 2x + 4) (4 * ln + x * ln) = ln(x + 2x + 4) (4ln + lnx) = ln(x + 2x + 4) Reorder the terms: 4ln + lnx = ln(4 + x + 2x) Combine like terms: x + 2x = 3x 4ln + lnx = ln(4 + 3x) 4ln + lnx = (4 * ln + 3x * ln) 4ln + lnx = (4ln + 3lnx) Add '-4ln' to each side of the equation. 4ln + -4ln + lnx = 4ln + -4ln + 3lnx Combine like terms: 4ln + -4ln = 0 0 + lnx = 4ln + -4ln + 3lnx lnx = 4ln + -4ln + 3lnx Combine like terms: 4ln + -4ln = 0 lnx = 0 + 3lnx lnx = 3lnx Solving lnx = 3lnx Solving for variable 'l'. Move all terms containing l to the left, all other terms to the right. Add '-3lnx' to each side of the equation. lnx + -3lnx = 3lnx + -3lnx Combine like terms: lnx + -3lnx = -2lnx -2lnx = 3lnx + -3lnx Combine like terms: 3lnx + -3lnx = 0 -2lnx = 0 Divide each side by '-2'. lnx = 0 Simplifying lnx = 0 The solution to this equation could not be determined.
