Answer:
[Adding any number to a negative number results in subtraction between the two numbers
When you add a positive number, you move to the right on the number line.
When you add a negative number, you move to the left on the number line.]
Hence, x+y =10/14 - 21/14 [Taking L.C.M within the denominators]
x+y = -11/14
Similarly,
R.H.S.=y+x= (-3/2) + 5/7
=-21/14+10/14 [Taking L.C.M within the denominators]
y+x =-11/14
Thus, we can say that x+y=y+x when x=5/7 and y= (-3/2)
