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
[tex]2d\text{.}[/tex]Now, we have to subtract 13 6/7 the above expression from the above expression:
[tex]2d-13\frac{6}{7}.[/tex]Answer:
[tex]2d-13\frac{6}{7}.[/tex]
