    Find the largest of three consecutive even integers when six times the first integers is equal to five times the middle integer.

    Let the first of the 3 consecutive even integers be n.
    The second consecutive even integer is n + 2.
    The third (largest) consecutive even integer is n + 4.

    We are given 6n = 5(n + 2).

    Multiply through on the right side, and we get:
    6n = 5n + 10

    Typing 6n = 5n + 10 into the search engine, we get n = 10.

    Remember, n was our smallest of 3 consecutive even integers. So the largest is:
    n + 4
    10 + 4
    14
