    what integer is tripled when 9 is added to 3 fourths of it?

    Let the integer be n. Tripling an integer means multiplying it by 3. We're given:
    3n = 3n/4 + 9

    Since 3 = 12/4, we have:
    12n/4 = 3n/4 + 9

    Subtract 3n/4 from each side:
    9n/4 = 9

    Typing this equation into the search engine, we get:
    n = 4
