The sum of two numbers is 54 , and the difference between the numbers is 4 . Find the numbers.

Step 1 ：We have two equations here: \(x + y = 54\) and \(x - y = 4\).

Step 2 ：We can solve these equations simultaneously to find the values of x and y.

Step 3 ：By solving the equations, we find that \(x = 29\) and \(y = 25\).

Step 4 ：Final Answer: The two numbers are \(\boxed{29}\) and \(\boxed{25}\).
