Simplifying log(7x + 9) = 1 + log(x + -1) Reorder the terms: glo(9 + 7x) = 1 + log(x + -1) (9 * glo + 7x * glo) = 1 + log(x + -1) (9glo + 7glox) = 1 + log(x + -1) Reorder the terms: 9glo + 7glox = 1 + glo(-1 + x) 9glo + 7glox = 1 + (-1 * glo + x * glo) 9glo + 7glox = 1 + (-1glo + glox) Solving 9glo + 7glox = 1 + -1glo + glox Solving for variable 'g'. Move all terms containing g to the left, all other terms to the right. Add 'glo' to each side of the equation. 9glo + glo + 7glox = 1 + -1glo + glo + glox Combine like terms: 9glo + glo = 10glo 10glo + 7glox = 1 + -1glo + glo + glox Combine like terms: -1glo + glo = 0 10glo + 7glox = 1 + 0 + glox 10glo + 7glox = 1 + glox Add '-1glox' to each side of the equation. 10glo + 7glox + -1glox = 1 + glox + -1glox Combine like terms: 7glox + -1glox = 6glox 10glo + 6glox = 1 + glox + -1glox Combine like terms: glox + -1glox = 0 10glo + 6glox = 1 + 0 10glo + 6glox = 1 Reorder the terms: -1 + 10glo + 6glox = 1 + -1 Combine like terms: 1 + -1 = 0 -1 + 10glo + 6glox = 0 The solution to this equation could not be determined.
