甲車(chē)隊(duì)有50輛汽車(chē),乙車(chē)隊(duì)有41輛汽車(chē),如果要使乙車(chē)隊(duì)數(shù)比甲車(chē)隊(duì)車(chē)數(shù)的2倍還多1輛,應(yīng)從甲車(chē)隊(duì)調(diào)多少輛車(chē)到乙車(chē)隊(duì)?
解:設(shè)應(yīng)從甲車(chē)隊(duì)調(diào)x輛車(chē)到乙車(chē)隊(duì),
根據(jù)題意,得方程41+x=2(50﹣x)+1
解之得:x=20.
答:應(yīng)從甲車(chē)隊(duì)調(diào)20輛車(chē)到乙車(chē)隊(duì).
