Sarah is exactly 12 years older than twice Jimmy's age. How many years from now will Sarah be only twice Jimmy's age?
***
At present:
x=Jimmy's age
2x+12=Sarah's age
let y=Years Sarah be only twice Jimmy's age.
2x+12+y=2(x+y)
2x+12+y=2x+2y
y=12
Years from now Sarah will be only twice Jimmy's age=12
Note: It doesn't matter what their present ages are.
