Sheri’s age in 20 years time will be the same as terry’s age is now. ten years from now, terry’s age will be twice sheri’s age. what are their ages presently?

Sheri's age = 10

Terry's age = 30

Step-by-step explanation:

Sheri’s age in 20 years time will be the same as Terry’s age is now. Ten years from now.

Let T be the Terry's age

And S be the Sheri's age

Ten years from now, Terry’s age will be twice Sheri’s age

Subtract 10 from both sides

Now we replace T by 2S+10 in the first equation

Subtract S from both sides

Subtract 10 from both sides

S= 10

Sheri's age = 10

Terry's age = 30
