Question

7n = 21 then, n = 3. Which property is shown below?

Answer 1

The question is,

`\begin{gathered} 7n=21,\text{ then} \\ n=3 \\ \text{This is the division property} \end{gathered}`

This is because, in order to simplify this equation, you have to divide both sides of the equation by the same value. In this case when you divide both sides of the equation by 7, then you arrive at;

`\begin{gathered} (7n)/(7)=(21)/(7) \\ n=3 \end{gathered}`
