Question

Verify that –(-x) is the same value as x for 21/112

Answer 1

Solution → x = 21 / 112

Additive inverse of x = - x = - 21 / 112

•

$\frac{21}{112} + ( \frac{ - 21}{112} ) = 0 \\ additive \: inverse \: of \: - x = - ( - x) = - ( \frac{21}{112} = \frac{21}{112} \\ \\ check \: \: ( \frac{ - 21}{112} ) + ( \frac{21}{112} = 0$

Thus, - ( - x ) = x

hence proved..
