Erica is 7 years older than Allen. In 5 years time Erica will be twice as old as Allen. How old is Erica now​

9 years old

Step-by-step explanation:

let Allen's age be n then Erica is n + 7

In 5 years their ages will be

n + 5 and n + 7 + 5 , also

n + 7 + 5 = 2(n + 5)

n + 12 = 2n + 10 ( subtract n from both sides )

12 = n + 10 ( subtract 10 from both sides )

2 = n

Thus Allen is 2 and Erica is 2 + 7 = 9 years old
