    Solution:

    Given statement,
    Twice a number decreased by 217 equals 373.
    Let y be the number.
    Twice the number y is 2×y.
    ⇒ 2y
    Now, decreasing 2y by 217 means subtracting 217 from 2y.
    ⇒ 2y-217
    And, the result is equal to 373.
    ⇒ 2y-217=373
    Hence, the correct option is 3.
