Question

verify that -(-x)=x for 1. x=2/15 2.-13/17​

Answer 1

Answer:

Step-by-step explanation:

1.-(-2/15)=2/15

2.-(-13/17)=13/17

Answer 2

Step-by-step explanation:

here X. = 2/15

so,. if there is a minus sign before the bracket then the sign inside the bracket changes to its opposite so

here , - (- X) = - (-2/15)

= 2/15

= X

Similarly ,

for X = - 13/17

here ,. - (-X) = - (-13/17)

= 13/17

hence proved
