​

Answer 1

Answer:

Let two numbers be x and y

according to question

1st equation

x+y=22

x=22-y

2nd equation

x-y=2

put value of x from equation 1

22-y-y=2

22-2=2y

20=2y

y=10

now, x=22-10

x=12

two numbers are 12 and 10

Answer 2

x+y--22 and x-y--2(by elemination method)

2×--24

X--12(put in the above question)

So y=10
