As given by the question

There are given that the sentence: twice the difference of a number

Now

Twice the difference means to multiply the difference by two

According to the given sentence;

It explains the difference being between the unknown number (b) and 2

So, the answer is said to be 8.

Then,

We need to put the difference (b - 2) and multiply it by 2 and equal to 8

So,

`2(b-2)=8`

Hence, the equation is 2(b - 2) = 8.
