Answer 2

Let Age of Gabriela=X years

Kevin age is 2 times Gabriela Age.

Kevin Age=2x years

12 years Ago

Gabriela Age was=(x-12) years

Kevin Age was=(2x-12) years

Kevin age was also 6 times Gabriela age

So,

Kevin Age 12 years ago=6×Gabriela Age 12 years ago

2x-12=6(x-12)

2x-12=6x-72

2x-6x=-72+12

-4x=-60

X=-60/-4

X=15

Age of Gabriela is=X=15 years
