Question

Evaluate the expression 2n - 6 if n = 16.

Answer 1

26

Explanation:

This is the answer because:

1) First, we have to substitue the value that stand for n into the equation:

2(16) - 6

2) Next, we have to follow the order of operations in order to find the answer:

1. 2 x 16 = 32

2. 32 - 6 = 26

Therefore, the answer is 26.

Hope this helps! :D

Answer 2

`26`

Explanation:

`2n-6`

Given that:

`n=16`

To evaluate the expression, we must simply substitute the given value of
`n`, which is
`16`, for
`n`:

`2(16)-6`

Multiply:

`32-6`

Subtract:

`26`

-

To check your work, simply set the given expression equal to our solution,
`26`:

`2n-6=26`

Add
`6` to both sides of the equation:

`2n=32`

Divide both sides of the equation by the coefficient of
`n`, which is
`2`:

`n=16`

Since it matches the given value of
`n`, our solution is correct!
