If x = 5, what does 4x - 2 represent?

If x = 5, what does 4x - 2 represent?

• A. 18
• B. 20
• C. 22
• D. 24

Answer: (C)

To determine what 4x - 2 represents when x is equal to 5, you start by substituting 5 for x in the expression. This involves performing the following calculations: 1. Substitute the value of x: 4(5) - 2 2. Multiply 4 by 5: 20 - 2 3. Subtract 2 from 20: 18 Therefore, the expression 4x - 2 evaluates to 18 when x = 5. The correct interpretation of the expression reflects the sequence of operations, demonstrating that when you multiply 4 by the value of x and then subtract 2, the final result is 18. This clarifies that if the answer provided is 22, it doesn't match the calculated value. Hence, the outcome shows how the expression is evaluated step-by-step to derive the final numeric result based on given variables.
