Answer:

Step-by-step explanation:

Let x years ago man,s age was six times of his son

Then,we can write it as

42-x=6(12-x)

42-x=72-6x

6x-x=72-42

5x=30

x=30/5=6 years ago man,s age was six times than his son

We can see

Man,s age six years ago 42-6=36

Son,s age six years ago 12-6=6

Hence proved
