Answer:

The numbers are 27 and 48.  Hope it helps :):)

Step-by-step explanation:

Let x = the first number

y = the second number  

The sum of two numbers is 75.

x+y=75  

The difference between those numbers is 21.

x-y=21  

x+y=75

x-y=21

2x=96

 

x=48  

Substitute x with 48

48+y=75

y=75-48

y=27  

The numbers are 27 and 48.  

Check

48-27 = 21

21 = 21
