Question

verify the property x+y=y+x by taking x=-2/5and y= -9/10​

Answer 1

X+y=y+X

-2/5-9/10=-9/10-2/5

-4-9/10=-9-4/10

-13/10=-13/10

Hope it will help you

Answer 2

Step-by-step explanation:

LHS- x+y

putting x=-2/5,y=-9/10

we get ,

= -2/5+(-9/10)

= -2/5-9/10

= -4-9/10

= -13/10

RHS- y+x

putting y= -9/10, x=-2/5

we get ,

-9/10+(-2/5)

-9/10-2/

-9-3/10

-13/10

Hence, RHS=LHS

verified.
