Given x+y = 120--------(1) , x-y = -22-----(2)

Now , (1)+(2) = x+y=120

(+) x-y = -22

⇒2x = 98

⇒x=98/2 = 49

Now , from (1), x+y=120

⇒49+y = 120

⇒y = 120-49 = 71

Therefore , the two numbers are 49 and 71 .

now from the given data

x+y=120...........(1)

x-y=-22.........(2)

we cen do this sum by either of the two methods namely elemenation and susbstitution

elemenation method

(1)+(2)

x+y=120

x-y=-22

⇒2x=98

x=98/2

**x=49**

(1)

x+y=120

49+y=120

y=120-49

**y=71**

therefor the two numbers are 49 and 71
