A father's age is 4 times that of his son. 4 years ago it was 6 times as great. Find their ages. I said the son's age was x, and the father's age was 4x. Then I wrote this equation: 4x-4 =6x, but the answer doesn't make sense.

The expression "4x - 4" is "the father's age, four years ago". The expression "6x" is "six times the son's age

Now that I reaad it again, I think it means 6 times his aage then.

So, following the set-up logic explained

. . .ages now:

. . . . .son: x

. . . . .father: 4x

. . .ages then:

. . . . .son: ??

. . . . .father: 4x - 4

Complete the table, and then insert the appropriate bits into the sentence:

. . . . .(father's age then) was (six)times (son's age then)

Then solve the equation.
