Mark me as a Brainlist pls

Step-by-step explanation:

x + y = y + x by taking : x = -6/5 , y = 3/7

x + y = y + x \\  =  >  \frac{ - 6}{5}  +  \frac{3}{7}  =  \frac{3}{7}  + ( -  \frac{6}{5} ) \\  =  > taking \: lcm \: we \: get \\  =  >  \frac{ - 42 + 15}{35}  =  \frac{15 - 42}{35}  \\  =  >  \frac{ - 27}{35}  = \frac{ - 27}{35}  \\ lhs \:  = rhs \\

x + y  = y + x \\ hence \: proved \\

it is commutative property :- a + b = b + a
