Question

If x = 2 n + 1, what is the value of x when n = 10?

Answer 1

x = 21

Explanation:

Given that,

n = 10

To find the value of x, replace n with 10 and solve the expression.

x = 2n + 1

x = 2 × 10 + 1

x = 20 + 1

x = 21

Answer 2

QUESTION

If x = 2n + 1, what is the value of x when n = 10?

EXPLANATION

To find the value of x when n is equal to 20, all you have to do is substitute n with 10 in the equation you are given.

Substitute:

`\bf x=2(10)+1`

Your new equation is
`\bf x=2(10)+1`

Now you need to multiply the 2 and 10 to take out the parentheses.

`\bf 10 * 2=20`

Your new equation is
`\bf x=20+1`

Lastly, you have to add 20 and 1

`\bf 20+1=21`

That means your answer is x = 21
