The sum of two numbers is 75. the difference between those numbers is 21. what are the two numbers?

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

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72
