1. Fix the statement of the problem, by using an inequality symbol, not an = sign.
2. You have already received highly relevant guidance on another problem of this type. All you need to do first, perhaps, is to clear fractions, i.e. multiply all terms by 15 so that all denominators disappear; then distribute & solve.
3. Don't hesitate to study your textbook carefully. If for some reason there's no textbook, you and your parents have a legitimate complaint!
