Question

For x= 1/5 and y= 3/7, verify that -(x+y) =(-x) +(-y)​

Answer 1

Answer:

Step-by-step explanation:

Put the value of x and y

-(1/5+3/7)=-1/5+(-3/7)

-(7+15/35)=-7-15/35

-22/35=-22/35

Answer 2

Answer:

L.H.S= -(x+y)

= -(1/5+3/7)

= -(1×7+3×5)/35

= -(7+15)/35

= -22/35

R.H.S= (-1/5)+(-3/7)

= -1/5-3\7

=( -1×7-3×5)/35

= (-7-15)/35

= -22/35

Hence L.H.S=R.H.S
