Question 1121612
.
<pre>
From the condition, the father is 36-12 = 24 years older than Jodi.


Hence, when the father age will be 24*2 = 48,  he will be twice Jodi's age.


It will happen in  48-36 = 12 years.


<U>Check</U>.  In 12 years father will be  36+12 = 48 years old;  Jodi will be 12+12 = 24 years old.

           {{{48/24}}} = 2.   ! Correct !
</pre>


The formal algebra solution is <U>THIS</U>.


<pre>
Let x be the number of years under the question.  Then


36+x = 2*(12+x)  ====>


36 + x = 2*12 + 2x


36 + x = 24 + 2x


36 - 24 = 2x - x  ====>  x = 12   <<<---=== the same answer.
