Question

verify that -(-x)=x for
(i) x=11/15
(ii)x= -13/17

Answer 1

Step-by-step explanation:

-(-x) =x

(1) LHS:-(-x) =-(-11/15)=11/15

RHS:x=11/15

LHS=RHS

(2)LHS:-(-x) =-(13/17)=-13/17

RHS:x=-13/17

LHS=RHS

Answer 2

Step-by-step explanation:

To verify -(-x)=x

1.11/15

-(-11/15)=11/15

11/15=11/15

LHS=RHS

2.-13/17

-(-(-13/17)=13/17

13/17=13/17

LHS=RHS
