To solve the equation \( |x| + 4 = 7 \), we start by isolating the absolute value:
\[ |x| + 4 = 7 \]
Subtract 4 from both sides:
\[ |x| = 3 \]
The absolute value equation \( |x| = 3 \) means that \( x \) can be either 3 or -3. Therefore, the two values of \( x \) that make the equation true are:
\[ 3 \text{ and } -3 \]
Among the responses, the correct answer is:
3 and -3
