Question

solve for x.
x - 7 = 2
x = ?

Explanation:

Step1: Add 7 to both sides

To isolate \( x \), we add 7 to both sides of the equation \( x - 7 = 2 \). This gives us \( x - 7 + 7 = 2 + 7 \).

Step2: Simplify both sides

Simplifying the left side, \( -7 + 7 = 0 \), so we have \( x = 2 + 7 \). Simplifying the right side, \( 2 + 7 = 9 \).

Answer:

\( x = 9 \)
