Question

Verify that (x + y) = (-x) + (-y), when (i) x =3/4
y=6/7
X=-3/4
Y=-6/7​

Answer 1

Answer:

yes they are equal

Step-by-step explanation:

(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:

1.(x+y) substituting the value

(6/7+3/4) = (24+21) /28 = 45/28

2. (-3/4-6/7=(-21/-24/28= -45/28
