To find the two numbers, we can set up a system of equations based on the given information.
Let's assume the two numbers are represented by variables x and y.
From the given information:
1) The sum of the two numbers is 28: x + y = 28.
2) The difference between the two numbers is 4: x - y = 4.
To solve this system, we can use the method of substitution or elimination.
Let's use the method of elimination. We can add the two equations together to eliminate the y term:
(x + y) + (x - y) = 28 + 4
2x = 32
Divide both sides of the equation by 2:
2x / 2 = 32 / 2
x = 16
Substitute this value back into one of the original equations (x + y = 28) to solve for y:
16 + y = 28
y = 28 - 16
y = 12
Therefore, the two numbers are 16 and 12.
