Answer:
Step-by-step explanation:
One number can be x, and the other number can be y. Then we know the following
x + y = 28
x - y = 4
Adding the two equations together by way of the Elimination Method produces
2x = 32
x = 16
Now, plug this into either of the two equations above. Let's choose the first.
16 + y = 28
y = 12
The two numbers are 12 and 16
12 + 16 = 28
16 - 12 = 4
