Question

Verify that -(-a)=a is true for a =
-21/-19

Answer 1

Answer

a =-19/21

a =-19/21a/q

a =-19/21a/q-(-a) = a

a =-19/21a/q-(-a) = a-(-19/21) = -19/21

a =-19/21a/q-(-a) = a-(-19/21) = -19/2119/21 = -19/21

a =-19/21a/q-(-a) = a-(-19/21) = -19/2119/21 = -19/21LHS is not equal to RHS....

a =-19/21a/q-(-a) = a-(-19/21) = -19/2119/21 = -19/21LHS is not equal to RHS....Hence,-(-a)=a is not true for a = -19/21

a =-19/21a/q-(-a) = a-(-19/21) = -19/2119/21 = -19/21LHS is not equal to RHS....Hence,-(-a)=a is not true for a = -19/21hope it helps you
