Bill tells Matt that he has 3 kids. This means that in this item, we have three unknowns, those are the ages of the three kids. First, the product of the ages is 72.
(x)(y)(z) = 72
Also, for the sum of their ages, we have
x + y + z =?
There are three variables in the equation which means that 3 equations should also be presented to determine the ages of the three children.
I’m pretty sure it 19 :-)
