Let's solve the inequality step-by-step. Starting from the given inequality:
\[ 6 + 3x \leq 24 \]
La’Shondra first subtracts 6 from both sides:
\[ 3x \leq 24 - 6 \] \[ 3x \leq 18 \]
Next, she will divide both sides of the inequality by a number to isolate \( x \). To solve for \( x \), she divides both sides by 3:
\[ x \leq \frac{18}{3} \] \[ x \leq 6 \]
The number that she divides both sides by is 3.
