Let
and
represent the pairs of whole numbers that have a sum of 40.
This implies that,
This a single linear equation in two variable. To solve this kind of equation, we make one variable the subject. Say,
Since,
is a whole number, the domain of the above function is the set of whole numbers.
In order to get a solution, we choose a value for x and then solve for corresponding value of y.
If
This means,
Hence,
is one possible solution.
Since the set of whole numbers we can choose for
is infinitely many,
