To answer this question, we will translate to algebraic notation by parts.
First, we consider the second part of the statement:
The product of 2 and a number d, in algebraic notation the statement is
![2d\text{.}](https://img.qammunity.org/2023/formulas/mathematics/college/a90e530dbrbjsth5nxer2443xa5hbv4u02.png)
Now, we have to subtract 13 6/7 the above expression from the above expression:
![2d-13(6)/(7).](https://img.qammunity.org/2023/formulas/mathematics/college/mxhk1vjrcqptu6bbouxs8qid1pzfha0ugt.png)
Answer:
![2d-13(6)/(7).](https://img.qammunity.org/2023/formulas/mathematics/college/mxhk1vjrcqptu6bbouxs8qid1pzfha0ugt.png)
