.
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.
Check. In 12 years father will be 36+12 = 48 years old; Jodi will be 12+12 = 24 years old.
= 2. ! Correct !
The formal algebra solution is THIS.
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.
