Simplifying ln(21 + x) + 7 = 4ln(x) (21 * ln + x * ln) + 7 = 4ln(x) (21ln + lnx) + 7 = 4ln(x) Reorder the terms: 7 + 21ln + lnx = 4ln(x) Multiply ln * x 7 + 21ln + lnx = 4lnx Solving 7 + 21ln + lnx = 4lnx Solving for variable 'l'. Move all terms containing l to the left, all other terms to the right. Add '-4lnx' to each side of the equation. 7 + 21ln + lnx + -4lnx = 4lnx + -4lnx Combine like terms: lnx + -4lnx = -3lnx 7 + 21ln + -3lnx = 4lnx + -4lnx Combine like terms: 4lnx + -4lnx = 0 7 + 21ln + -3lnx = 0 Add '-7' to each side of the equation. 7 + 21ln + -7 + -3lnx = 0 + -7 Reorder the terms: 7 + -7 + 21ln + -3lnx = 0 + -7 Combine like terms: 7 + -7 = 0 0 + 21ln + -3lnx = 0 + -7 21ln + -3lnx = 0 + -7 Combine like terms: 0 + -7 = -7 21ln + -3lnx = -7 Reorder the terms: 7 + 21ln + -3lnx = -7 + 7 Combine like terms: -7 + 7 = 0 7 + 21ln + -3lnx = 0 The solution to this equation could not be determined.
