Question

the sum of two integers is 45 . if one of them is 21 , find the other​

Answer 1

Answer:

24

Step-by-step explanation:

Let X and Y be the integers

then first equation is

X+Y=45

21+Y=45

hence Y=45-21

=24

Answer 2

Answer:

heya!!

Here is the answer...

let one number be 21

And another num be x+21

Given that the sum of two integers is45

Therefore = x+21+21=45

=x+42=45

=x=45-42

=x=3

Therefore another num is 3

substitute x value in x+21= 3+21=24

since 21+24=45✓✓
