Question

X=3/7&y=-5/11,verify that (-x)+(-y)=-(x+y)

Answer 1

Answer:

Step-by-step explanation:

x =3/7 , and y =-5/11

verify that

(-x) + (- y) = -(x + y)

LHS=(-3/7)+(-(-5/11))

= -3/7+5/11

Taking LCM of 7 and 11 =7*11=77

=1/77(-3*11+5*7)

=1/77(-33+35)

=-2/77

Now RHS=-(3/7-5/11)

=-1/77( 3*11-5*7)

=-1/77(33-35)

=-1/77(-2)

=2/77

We get

LHS= RHS

Hence verified

Answer 2

Answer:

x=3/7

y=-5/11

so 1st -x+ -y

= -3/7+5/11

=2/77

now 2 nd

-(x+y)

=-(3/7+(-5/11))

=-3/7+5/11

=2/77

hence proved hope it's helpful
