Simplifying ln(4 + 1) = ln(2x + 5) Combine like terms: 4 + 1 = 5 ln(5) = ln(2x + 5) Reorder the terms for easier multiplication: 5ln = ln(2x + 5) Reorder the terms: 5ln = ln(5 + 2x) 5ln = (5 * ln + 2x * ln) 5ln = (5ln + 2lnx) Add '-5ln' to each side of the equation. 5ln + -5ln = 5ln + -5ln + 2lnx Combine like terms: 5ln + -5ln = 0 0 = 5ln + -5ln + 2lnx Combine like terms: 5ln + -5ln = 0 0 = 0 + 2lnx 0 = 2lnx Solving 0 = 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. 0 + -2lnx = 2lnx + -2lnx Remove the zero: -2lnx = 2lnx + -2lnx Combine like terms: 2lnx + -2lnx = 0 -2lnx = 0 Divide each side by '-2'. lnx = 0 Simplifying lnx = 0 The solution to this equation could not be determined.
