Sam is now 5 times as old as his son Paul. Four years ago, the product of their ages was 52. Find their present ages.
Note: Remember that the term product means the result of multiplying two numbers and sum is the result of addition.
Let x be the age of Paul
5x = the age of Sam
x - 4 = the age of Paul 4 years ago
5x - 4 = the age of Sam 4 years ago
5x+6=0 and x−6=0
5x+6=0 will yield a negative value for x, so this is not possible solution.
x=6 : the age of Paul
5x=5(6)=30 : the age of Sam
