9. Verify that -(x + y) = (-x) + (-y), when (a) x = 3/4, y = 6/7 (b) x

1.	9. Verify that -(x + y) = (-x) + (-y), when (a) x = 3/4, y = 6/7 (b) x=-3/4, y=-6/7
Answer» ANSWER: A. -(3/4+6/7)=(-3/4)+(-6/7) remove the brackets -3/4+6/7=-3/4-6/7 now do L.C.M for the denominators. you will GET 28. -21/28+24/28=-21/28-24/28 23/28 is not EQUAL to -45/28 hope it helps..

Answer»

ANSWER:

A. -(3/4+6/7)=(-3/4)+(-6/7)

remove the brackets

-3/4+6/7=-3/4-6/7

now do L.C.M for the denominators.

you will GET 28.

-21/28+24/28=-21/28-24/28

23/28 is not EQUAL to -45/28

hope it helps..
