Question

If some of two numbers is 21 and their difference is 5​

Answer 1

Answer:

X+Y = 21 ---> Y = 21-x

X-y = 5

x - (21-x) = 5

2x - 21 = 5

2x = 26

x = 13

13 and 8

Answer 2

Answer:

your answer is one of the number is 13and second number is 8

Step-by-step explanation:

let the numbers be x and y

therefore given that

x + y = 21 .................1

x - y= 5 ..................2

So subtracting 2 from 1

= 2x= 26

So X = 13

from 1

y=21-13

y=8
