Kevin is 2 times as old as Gabriela. 12 years ago, Kevin was 6 times as old as Gabriela. How old is Gabriela now?

gabrielas age is 15

Step-by-step explanation:

Let Gabriela's age be x, then Kelvins age is 2x

12 years ago, Gabriela's age was x - 12 and Kelvin's age was 6(x - 12)

i.e. 6x - 72 = 2x - 12

4x = 60

x = 60/4 = 15

Therefore, Kelvin's age is 2(15) = 30 years old
