Step-by-step explanation:

× + y =y + × .

-8 +9/2 =9/2 + (-8)

(-16 + 9)/2 = (9 +(-16)/2

-7/2 =(9 -16)/2

-7/2 = -7/2. proved.

Answer 2

Step-by-step explanation:

Given x=8, y=9/2

x+y= 8 + 9/2

= 16+9/2 (TAKING LCM)

=25/2

=12.5

NOW, y+x= 9/2+8

=9+16/2 (taking lcm)

=25/2

=12.5

Hence, x+y = y+x
