A number line with arrows at both the ends ranges from negative 10 to 10 in unit increments. A closed circle is marked on the tick line above 4. A line is drawn from 4 toward 10 with an arrow at the end.

To solve the inequality \(x + 3 \leq 7\), we first isolate \(x\):

\[ x + 3 \leq 7 \ x \leq 7 - 3 \ x \leq 4 \]

The solution to this inequality is all values of \(x\) that are less than or equal to 4.

On a number line, this is represented by:

  • A closed circle at 4 (indicating that 4 is included in the solution)
  • A line extending to the left (toward negative infinity) from 4, indicating all values less than 4.

Based on the provided descriptions, the correct representation of the solution \(x \leq 4\) is:

A number line with arrows at both the ends ranges from negative 10 to 10 in unit increments. A closed circle is marked on the tick line above 4. A line is drawn from 4 toward negative 10 with an arrow at the end.
