Marion is solving the equation 9x − 6 = 12

Question

9
𝑥

−

6

=

12
. As a first step, she adds 6 to both sides of the equation. In the next step, by what value does each side need to be divided? (1 point)/

Answer 1

Marion's equation is \( 9x - 6 = 12 \). After adding 6 to both sides, the equation becomes:

\[ 9x - 6 + 6 = 12 + 6 \]

This simplifies to:

\[ 9x = 18 \]

Now, to isolate \( x \), Marion needs to divide both sides of the equation by the coefficient of \( x \), which is 9. Therefore, each side needs to be divided by:

\[ 9 \]

So, the value by which each side should be divided is 9.
