Twice the difference of a number and 8 is equal to 2 .

Question

What would the answer be if it was translated into an equation?

Answer 1

You can call an unknown number 'x'. The difference of a number and 8 can then be written as 'x-8'. Twice that amount would be 2(x-8). If it's equal to 2, you can say 2(x-8)=2. That is your equation.
