Question

1.verify x+y=y+x for following values of x and y.
i.x=5/7,y=-3/2

IF YOU ANSWER I MARK YOU BRAINSLIST​

Answer 1

Answer :-

5/7 + (- 3/2) = (-3/2) + 5/7

=> 5/7 - 3/2 = -3/2 + 5/7

=> -11/14 = -11/14

Answer 2

5/7-3/2=5/7-3/2(l.h.s=r.h.s)

given= x=5/7 , y= -3/2

verify=x+y=y+x

let,x+y(l.h.s)

and,y+x(r.h.s)

L.H.S. R.H.S

X+Y. Y+X

=5/7+(-3/2) =-3/2+5/7

=5/7-3/2. =5/7-3/2

so, another one

=>x+y=ytx

=>5/7-3/2=-3/2+5/7(given)

=>5/7-3/2=5/7-3/2

=>(10-21)/14=(10-21)/14

=>-11/14=-11/14(verified)
