Given the expression ‘6 more than twice a number’, what is the value of the expression if the number is equal to 5?

stepan [7]

Answer:

Expression: $2x + 6$

Value of the expression when $x = 5$ : $16$

Step-by-step explanation:

Let's first focus on the expression: '6 more than twice a number'. Twice a number is the same as saying two times a number. Let's have that number be represented by $x$ . Twice a number would mean $2x$ , and 6 more than that would just be $2x + 6$ .

We'll then plug in 5 for $x$ to get the value of the expressinn:

$2(5) + 6 = 10 + 6 = 16$
