Question

Select the reason that best supports Statement 9 in the given proof.

Answer 1

D. Division property of equality

Step-by-step explanation

From statement 8 to statement 9, the value of x was found. In statement 8 we have,

`9x=162`

To find x, we have to divide both sides by 9,

`\begin{gathered} (9x)/(9)=(162)/(9) \\ \\ x=18 \end{gathered}`

This is called the division property of equality because a division was made on both sides to maintain the equality.
