Answer 2

Step-by-step explanation:

(x+y)=(y+x)............ equation-1

put the value of x and y in equation 1

LHS = (7/3-3/7)

= (49-9/21)

= (40/21)

= 40/21..........equation 2

RHS = (-3/7+7/3)

= (-9+49/21)

= (40/21)

= 40/21..........equation 3

Equation 2=Equation 3

LHS=RHS

(x+y)=(y+x) Hence proved
