Question

what is $18x$ divided by 6?
$18x = 6(x - 1)$
$\frac{18x}{6}=\frac{6(x - 1)}{6}$
$\square x \\ x - 1$

Explanation:

Step1: Simplify $\frac{18x}{6}$

$\frac{18x}{6} = 3x$

Step2: Simplify $\frac{6(x-1)}{6}$

$\frac{6(x-1)}{6} = x-1$

Step3: Match the simplified terms

The left side simplifies to $3x$, so the blank corresponds to the coefficient of $x$.

Answer:

$3$
