verify that -(-x)=x for, x=11/15​

Answers 1

Step-by-step explanation:

(i) x = 11/15(i) x = 11/15-(-x) = -(-11/15)(i) x = 11/15-(-x) = -(-11/15)= 11/15(i) x = 11/15-(-x) = -(-11/15)= 11/15= x(i) x = 11/15-(-x) = -(-11/15)= 11/15= xHence proved(i) x = 11/15-(-x) = -(-11/15)= 11/15= xHence proved(ii) x = -13/7(i) x = 11/15-(-x) = -(-11/15)= 11/15= xHence proved(ii) x = -13/7-(-x) = -[-(-13/7)](i) x = 11/15-(-x) = -(-11/15)= 11/15= xHence proved(ii) x = -13/7-(-x) = -[-(-13/7)]= -13/7(i) x = 11/15-(-x) = -(-11/15)= 11/15= xHence proved(ii) x = -13/7-(-x) = -[-(-13/7)]= -13/7= x
