If 4 is the result of subtracting 2 from a number, what is the equation to represent this?

• A. x−2=4
• B. 2−x=4
• C. 4+x=2
• D. x+2=4

Answer: (A)

The scenario describes a relationship where a number, represented as \( x \), has 2 subtracted from it, resulting in 4. This can be translated into an equation. When we subtract 2 from \( x \), we express this as \( x - 2 \). According to the problem, this expression equals 4. Therefore, the correct equation is \( x - 2 = 4 \). This formulation captures the essential elements outlined in the problem: the number (\( x \)), the operation (subtraction of 2), and the outcome (resulting in 4). The choice reflects the correct mathematical representation of the given narrative.
