Question

verify that -(x) =x for (A.) x=11/15​

Answer 1

Answer:

x = 11/15

-(-x) = x

x = 11/15

Taking L. H. S = -(-x)

= -(-11/15)

Minus, minus become plus

= 11/15

R. H. S = x

Answer 2

Answer:

-(x) =x=11/15

Additive inverse of x=-(x) =-11/15

Check ;

=>11/15+(-11/15)

=>11/15-11/15

=>0

Additive inverse of - x=-(-x) =-(-11/15)

=>11/15

Check;

=>-11/15+11/15

=>0

Therefore,-(-x) =x

=>LHS=RHS
