    Thomas has taken 3 exams.

    The average of his 3 test scores was 198/3.

    His grade on the first test is 15 more than the second test.

    The sum of the first and the third test is 142.

    x = y + 15

    x + z = 142

    x + y + z = 198

    y = 56

    x = 71

    z = 71

    His scores on the 3 exams: 56, 71, and 71.
