Explanation:

Step1: Add 9 to both sides

To isolate the term with \( x \), we add 9 to both sides of the inequality \(-9 + 7x < 47\). This gives us \(-9 + 9 + 7x < 47 + 9\), which simplifies to \(7x < 56\).

Step2: Divide by 7

Next, we divide both sides of the inequality \(7x < 56\) by 7 to solve for \( x \). So, \(\frac{7x}{7} < \frac{56}{7}\), which simplifies to \(x < 8\).

Answer:

Inequality Notation: \( x < 8 \)
For the number line: We draw an open circle at 8 (since the inequality is strict, \( x < 8 \) not \( x \leq 8 \)) and shade the region to the left of 8 to represent all values of \( x \) that satisfy the inequality.
