Answer:
D. [tex]8N+7=2N[/tex]
Step-by-step explanation:
Let N represent the number.
We are asked to find the equation that satisfies the given description.
8 times the number would be [tex]8N[/tex].
The sum of eight times a number and seven would be [tex]8N+7[/tex].
Twice the number would be [tex]2N[/tex].
To find our required equation, we will equate the sum of eight times a number and seven to twice the number as:
[tex]8N+7=2N[/tex]
Therefore, option D is the correct choice.
