Question

hello everyone
today my question is....
find the sum and verify that x+y= y+x for given rational number.
(1) x = ,3 upon 28, y= 10 upon 11
​

Answer 1

Step-by-step explanation:

L.H.S= x+y

(subtituting the value)

(2/-7)+ (12/-35)

(2*5/-7*5) + (12/-35) ...(making denominator equal )

(10/-35) + (12/-35)

(-10-12/35)

-22/35( 1)

R.H.S=y+x

(12/-35) + (2/-7)

(12/-35) + (2*5/-7*5)

(12/-35) + (10/-35)

(-12-10/35)

-22/35 ...(2)

from 1 and 2

x+y = y+x
