Question

if x = -4/7 and y = 2/5 , then verify that : - (x + y) = (-x) + (-y)​

Answer 1

Answer: 48/35 ≠ -8/35

Step-by-step explanation = -(-4/7 + 2/5 ) = -(-4/7) + (-1*2/5)

=4/7+2/5 = 4/7 + -2/5

= 20/35 + 28/35 = 20/35 - 28/35

=48/35 ≠ -8/35

Answer 2

Answer:- Given, x = -4/7 and y = 2/5

L.H.S:- -( x + y ) = - ( -4/7 + 2/5 )

= ( 4/7 - 2/5 ) = [{-(-4/7) + {-(2/5)}]

= (-x) + (-y) = R.H.S (Proved).
