Step 1 :Let the larger number be represented by x and the smaller number by y.
Step 2 :The sum of the two numbers is 89, which can be represented by the equation x + y = 89.
Step 3 :The difference of the two numbers is 59, which can be represented by the equation x - y = 59.
Step 4 :Solving this system of equations gives the solution {x: 74, y: 15}.
Step 5 :Therefore, the larger number, \(x\) is \(\boxed{74}\). The smaller number, \(y\) is \(\boxed{15}\).
