Question

solve for x.
x + 4 = 13
x = ?

Explanation:

Step1: Subtract 4 from both sides

To isolate \( x \), we subtract 4 from both sides of the equation \( x + 4 = 13 \). This gives us \( x + 4 - 4 = 13 - 4 \).

Step2: Simplify both sides

Simplifying the left side, \( x + 4 - 4 \) becomes \( x \). Simplifying the right side, \( 13 - 4 = 9 \). So \( x = 9 \).

Answer:

\( 9 \)
