Question

can I get the full solution

Answer 1

Let Kate age be x
Then bob age becomes x+6
12 years ago
Bob age was twice the age of Kate
The age bob 12 years ago = x+6-12 =x-6
The age of Kate 12 years ago =x-12

According to the problem
x-6=2 (x-12)
x-6=2x-24
2x-x=24-6
×=18
×+6=18+6=24

Therefore the age of Kate is 18years and
The age of Bob is 24 years
