单选题

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

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。
