Simplifying ln(1 + -4x) + 5 = 7 (1 * ln + -4x * ln) + 5 = 7 (1ln + -4lnx) + 5 = 7 Reorder the terms: 5 + 1ln + -4lnx = 7 Solving 5 + 1ln + -4lnx = 7 Solving for variable 'l'. Move all terms containing l to the left, all other terms to the right. Add '-5' to each side of the equation. 5 + 1ln + -5 + -4lnx = 7 + -5 Reorder the terms: 5 + -5 + 1ln + -4lnx = 7 + -5 Combine like terms: 5 + -5 = 0 0 + 1ln + -4lnx = 7 + -5 1ln + -4lnx = 7 + -5 Combine like terms: 7 + -5 = 2 1ln + -4lnx = 2 Reorder the terms: -2 + 1ln + -4lnx = 2 + -2 Combine like terms: 2 + -2 = 0 -2 + 1ln + -4lnx = 0 The solution to this equation could not be determined.
