verify property x + y = y + x of rational number by taking
(1) x = 1/2 , y= 1/2
(2) x =-2/3 , y = -5/6
(3) x=-3/7 , y = 20/21
(4) x= -2/5 , y = -9/10

B^2=49. B=7. HENCE EQN. OF ELLIPSE IS X^2/64 + Y^2/49 = 1 .... so x=-1.....y=- 3.....and z=-1...you can check back ... 0 3 7 42 0 7 7 -38 1 solutions. Answer 9892 by venugopalramana(370) ..... HENCE D IS (-6+5)/2=-1/2 AND (-2+1)/2=-1/2

ans is (1)
1/2 and 1/2
because for x+y = y+x both x and y should be equal
1/2 and 1/2
because for x+y = y+x both x and y should be equal
BUT right full answer in detail
dear khush ......for a equation to be equal its
rhs and lhs should be equal
so for the given problem.....for x+y= y+x.......x and y should be equal
from the options given there is only one chance to be the equation will be correct......its 1/2 and 1/2 respectively
i hope u got the correct way
yes
good luck
And once again Thnks
☺:)
