    The following 3 equations are given:
    2b + 3g > f -—(1)
    m > b + 4g -—(2)
    f + b > m + 3g -—(3)

    Adding (1), (2), and (3), we get

    2b + 3g + m + f + b > f + b + 4g + m + 3g
    3b + 3g > b + 7g
    2b > 4g
    b > 2g -—(4)

    Now from eq.(1), we have
    2b + 3g > f
    Adding 3g to both sides, we get
    2b + 6g > f + 3g
    (b + 4g) + b + 2g > f + 3g

    Replacing (b + 4g) by (m) from eq.(2). The inequality will still hold.
    m + b + 2g > f + 3g

    replacing (2g) by (b) from eq.(4). The inequality will still hold.
    m + b + b > f + 3g
    m + 2b > f + 3g

    And that is what we needed to calculate.
    The mother and two boys will beat the father and three girls.
