Mai's mother was 28 when Mai was born. Mai is now 12 years old. In how many years will Mai's mother be twice Mai's Age

4

Step-by-step explanation:

Let x = the number of years

In x years, Mai's mother's age will be: 28 + x

and Mai's age will be: 12 + x

Then, 28 + x = 2 (12 + x)

Distribute the 2 28 + x = 24 + 2x

Subtract 24 from each side 4 + x = 2x

Subtract x from each side x = 4

In four years, Mai's mother will be twice Mai's age.

Check:

28 + 4 = 2 (12 + 4)

32 = 2 * 16

32 = 32
