Answer:

  36 ounces

Step-by-step explanation:

Let q represent the quantity of 30% solution required. The total amount of alcohol in the mix is ...

  30%·q + 35%·9 = 31%·(q +9)

  30q + 315 = 31q +279 . . . . multiply by 100 and eliminate parentheses

  36 = q . . . . . add -(279+30q) to both sides

36 ounces of 30% alcohol must be mixed to make the 31% solution.
