Let Gabriela's age be x, then Kelxins 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
Kevin was 2 times as old as Gabriela 12 years ago then Kevin was 6 times as old as Gabriela so now Kevin should be 36 years old because if you divide 12 by 2 it's gonna give you 6 so then he was 6 times old as Gabriela so now he's 36 years old
