Question 1210383
.
From a {{{highlight(cross(ceartain))}}} <U>certain</U> number 3 is subtracted {{{highlight(and)}}} the result is divided by 2. 
The final answer is 5. Find the number.

        <U>One way to solve</U>


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.    <<<---===  <U>ANSWER</U>



        <U>Another way to solve</U>


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

    {{{(x-3)/2}}} = 5.


To solve, multiply both sides by 2

    x - 3 = 10.


Now add  '3'  to both sides and get the  <U>ANSWER</U>   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.
