Question

solve the inequality $9 + 6x \leq 21$.

Explanation:

Step1: Subtract 9 from both sides

To isolate the term with \( x \), we subtract 9 from both sides of the inequality \( 9 + 6x \leq 21 \). This gives us \( 9 + 6x - 9 \leq 21 - 9 \), which simplifies to \( 6x \leq 12 \).

Step2: Divide both sides by 6

To solve for \( x \), we divide both sides of the inequality \( 6x \leq 12 \) by 6. This gives us \( \frac{6x}{6} \leq \frac{12}{6} \), which simplifies to \( x \leq 2 \).

Answer:

\( x \leq 2 \)
