Question

甲車隊(duì)有60輛汽車，乙車隊(duì)有50輛汽車，如果要使乙車隊(duì)車輛數(shù)比甲車隊(duì)車輛數(shù)的2倍還多5輛，那么應(yīng)從甲車隊(duì)調(diào)多少輛車到乙車隊(duì)?本題可設(shè)________，這時列出的方程為________．

Answer 1

答案：略
解析：

分析：設(shè)從甲車隊(duì)調(diào)x輛車到乙車隊(duì)，這時乙車隊(duì)有(50＋x)輛，甲車隊(duì)有(60－x)輛，由“乙車隊(duì)車輛數(shù)比甲車隊(duì)車輛數(shù)的2倍還多5輛”得方程50＋x=2(60－x)＋5．
