To find four numbers that add up to 11, we can set up an equation. Let the four numbers be represented by variables a, b, c, and d. We can write the equation as a + b + c + d = 11. To find a specific solution, we can choose numbers that satisfy this equation, such as 1, 2, 3, and 5, as 1 + 2 + 3 + 5 = 11.

Let's denote the two numbers as x and y. We can set up a system of equations: x + y = 18 and x - y = 4. By solving this system simultaneously, we can find that x = 11 and y = 7. Therefore, the two numbers that add up to 18 and subtract to 4 are 11 and 7.
