The larger of two numbers exceeds three times the smaller number by 2. The sum of twice the large and 4 times the smaller is 73. If a is the smaller number, which equation below determines the correct value of x?
A
4（3a+2）+2a=73
B
4 (3a+2) +2a=73
C
(6a+2) +4a=73
D
2 (3a+2) +4a=73
E
2 (3a-2) +4a=73
参考答案
参考解析
解析：
已知较小的数字是a，根据题目中已知的数量关系，较大的数字可以表示为3a+2，那么根据题干后半句，可列方程式为：2 (3a+2) +4a=73。
