Let  Kaye's  age  now  =  K

 

Then Cristina's age  =  3K -10

 

In two years we  have  that

 

3K  - 10  + 2  =  2K      simplify

 

3K - 8  =  2K        

 

3K - 2K  =8

 

K  = 8     .....Kaye is 8 yrs old

 

Check

 

Cristina's age  now  = 3(8)  -10  =  14

 

In two years Cristina =  16

 

And this is twice Kaye's age now
