Question

verify that (x+y)=(-x) +(-y)
When (a) x=3/4 ,y=6/7 (b) x=-3/4 ,y=-6/7

​

Answer 1

Answer:

Therefore:

( X + Y) = ( - X ) + ( -Y )

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

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

45/28 = -45/28

Answer 2

Answer:

Therefore:

( X + Y) = ( - X ) + ( -Y )

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

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

45/28 = -45/28
