甲、乙兩隊(duì)開展足球?qū)官悾?guī)定勝一場(chǎng)得3分,平一場(chǎng)得1分,負(fù)一場(chǎng)得0分,甲、乙兩隊(duì)共比賽6場(chǎng),甲隊(duì)保持不敗,共得14分,甲隊(duì)勝________場(chǎng).

4
分析:根據(jù)分?jǐn)?shù)可得等量關(guān)系為:甲勝場(chǎng)的得分+平場(chǎng)的得分=14,把相關(guān)數(shù)值代入求解即可.
解答:設(shè)甲隊(duì)勝了x場(chǎng),則平了(6-x)場(chǎng),
3x+(6-x)=14,
解得:x=4,
答:甲隊(duì)勝了4場(chǎng).
點(diǎn)評(píng):本題考查用一元一次方程解決實(shí)際問題,得到總得分的等量關(guān)系是解決本題的關(guān)鍵.
