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
