Simplifying (9r + 1) = ln(r2 + 9) Reorder the terms: (1 + 9r) = ln(r2 + 9) Remove parenthesis around (1 + 9r) 1 + 9r = ln(r2 + 9) Reorder the terms: 1 + 9r = ln(9 + r2) 1 + 9r = (9 * ln + r2 * ln) 1 + 9r = (9ln + lnr2) Solving 1 + 9r = 9ln + lnr2 Solving for variable 'r'. Reorder the terms: 1 + -9ln + -1lnr2 + 9r = 9ln + lnr2 + -9ln + -1lnr2 Reorder the terms: 1 + -9ln + -1lnr2 + 9r = 9ln + -9ln + lnr2 + -1lnr2 Combine like terms: 9ln + -9ln = 0 1 + -9ln + -1lnr2 + 9r = 0 + lnr2 + -1lnr2 1 + -9ln + -1lnr2 + 9r = lnr2 + -1lnr2 Combine like terms: lnr2 + -1lnr2 = 0 1 + -9ln + -1lnr2 + 9r = 0 The solution to this equation could not be determined.
