Question

The difference of twice a number and 2 is -21

Answer 1

2x-2= -21

Explanation:

Answer 2

-9.5

Explanation:

We can create an equation to represent this, where
`n` is the missing value.

`2n - 2 = -21`

Now we can solve for
`n` by isolating it on one side of the equation.

Add 2 to both sides:

`2n - 2 + 2 = -21+2\\\\2n = -19`

Divide both sides by 2:

`2n/2 = -19/2\\\\n = -9.5`

Hope this helped!
