Kayla is 2 times as old as gabriella. 12 years ago, kayla was 6 times as old as gabriella how old is gabriella now

i need step by step so i know how and get full credit

Gabriella is 10

First I took 12 and divided it by 6 for the 6 times then I just kept adding 2 years to each age with a 10 year spread between them until Kayla was 2 times older then Gabriella:

12:6=2

Ages of Gabriella and Kayla with a 2 year interval each time and 10 years apart:
