    nshs = sshs+5

    wshs = nshh + 6 = sshs + 11

    So nshs + wshs + sshs = 3*sshs + 16

    So sshs = 10, nshs = 15 and wshs = 21

    Answer 15.

    15 students are coming from North Springdale.

    Step-by-step explanation:

    Total students: 46

    South Springdale (SS) : X

    North Springdale (NS) : X + 5

    West Springdale (WS) : NS + 6 = X + 5 + 6

    3X + 5 + 5 + 6 = 46

    3X = 46 - 6 - 5 - 5

    3X = 30

    X = 30 / 3

    X = 10

    South Springdale: 10 students

    North Springdale: 15 students

    West Springdale: 21 students
