Question

What is the value of 3n - (2 + n)?
Options:
A) 5
B) 6
C) 4
D) 3

Answer 1

Our answer is 2n - 2.

`\Large\texttt{Explanation}`

We are asked to simplify the following expression -

3n - (2 + n)

First, distribute the minus -

3n - 2 - n

Next, combine the like terms -

3n - n - 2

2n - 2

`\therefore` 2n - 2

Answer 2

The answer depends on what 3n - (2 + n) is equal to, or what the value of n is.

Explanation:

There is no value for 3n - (2 + n) unless we know what the expression is equal to, or the value of n.

If 3n - (2 + n) was supposed to be equal to 0, then we can find a value:

3n - (2 + n) = 0

2n - 2 = 0

2n = 2

n = 1

Or if 3n - (2 + n) = 8

2n - 2 = 8

2n = 6

n = 3

Or if n = 1

3*1 - (2 + 1)

3 - 3 = 0
