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
