.
From a certain number 3 is subtracted the result is divided by 2.
The final answer is 5. Find the number.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 

        One way to solve


One way to solve is the backward method.


From the problem, before dividing by 2, the number was 5*2 = 10.


Hence, the original number was 10+3 = 13.    <<<---===  ANSWER



        Another way to solve


Another way to solve is via creating and solving an equation.


Let x be the original number.

Then write an equation as you read the problem

     = 5.


To solve, multiply both sides by 2

    x - 3 = 10.


Now add  '3'  to both sides and get the  ANSWER   x = 13.

Solved.

Both ways produce the same answer.

You may check that the answer is correct by making calculations with '13', described in the problem.
