Question

Twice the difference of a number and 7 is equal to 2 translate the sentence into an equation.

Answer 1

`2(n-7) = 2`

Explanation:

The statement says 2 multiplied by (n-7) is 2.

We say
`2(n-7) = 2`.

If you want to know the actual answer, it is
`2n-14 = 2` which is finally
`2n-16 = 0`.

From here, we can say
`2n=16` and simplified, this gives n = 8.
