Let x represent the number of years.

In x years, Sushi will be 5 + x years old, and the mother will be 28 + x.

At that time, the mothers age will be twice Sushi's, which gives:

28 + x = 2(5 + x)

28 + x = 10 + 2x

2x + 10 = x + 28

2x - x + 10 = 28

x + 10 = 28

x = 28 - 10

x = 18

Solution: In 18 years, Sushi's mother will be twice his age.

Check:

5 + 18 = 23

28 + 18 = 46 = 2 * 23
