Question

8、甲車(chē)隊(duì)有汽車(chē)56輛，乙車(chē)隊(duì)有汽車(chē)32輛，要使兩車(chē)隊(duì)汽車(chē)一樣多，設(shè)由甲隊(duì)調(diào)出x輛汽車(chē)給乙隊(duì)，則可得方程（　�。�

A、56+x=32-x

B、56-x=32+x

C、56-x=32

D、32+x=56

Answer 1

分析：首先要理解題意找出題中存在的等量關(guān)系：甲車(chē)隊(duì)原來(lái)的車(chē)輛數(shù)-調(diào)出的車(chē)輛數(shù)=乙車(chē)隊(duì)原來(lái)的車(chē)輛數(shù)+調(diào)入的車(chē)輛數(shù)，根據(jù)此列方程即可．

解答：解：設(shè)由甲隊(duì)調(diào)出x輛汽車(chē)給乙隊(duì)，則此時(shí)甲隊(duì)有汽車(chē)56-x輛，乙隊(duì)有汽車(chē)32+x輛．
根據(jù)“兩車(chē)隊(duì)汽車(chē)一樣多”得出方程為：56-x=32+x．
故選B．

點(diǎn)評(píng)：弄清楚車(chē)輛調(diào)動(dòng)后甲乙車(chē)隊(duì)各自的數(shù)量，然后根據(jù)題目給出的等量條件列出方程．
