and the man is four times the son's age, then the man's age is
.
Since we know the sum of their ages is 50, we can write the following expression:
.
To solve this we first combine the
terms on the left hand side.
We then need to isolate the
term by dividing both sides of the equation by 5 to obtain:
Recall that
was defined as the age of the son, so the son's age is 10. We can check this by determining that the man's age was 4 times the son's, so the man was 40 years old. The sum of 40 and 10 is 50, so we are correct.
