        甲、乙兩人修路隊(duì)共有76人,甲隊(duì)增加本隊(duì)人數(shù)的4倍,乙隊(duì)增加本隊(duì)人數(shù)的6倍后,兩隊(duì)共增加了384人,求甲、乙兩隊(duì)原有各有多少人?

        參考答案:
        設(shè)甲隊(duì)原有x人,乙隊(duì)原有(76-x)人,由題意得:
        4x+(76-x)×6=384,
        4x+76×6-6x=384,
        2x=456-384,
        2x=72,
        x=72÷2,
        x=36;
        則乙隊(duì)原有:76-36=40(人).
        答:甲隊(duì)原有36人,乙隊(duì)原有40人.
