Question

for x= -13/25 , verify that- (-x) = x with explanations ​

Answer 1

x = -13/25

so; -x = -(-13/25) = 13/25

now, -(-x) = -(13/25) = -13/25 = x

Hope you get it.....

Answer 2

we have x=-13/25 and we have to prove -(-x) = x first we put x value in -(-x) then from where we get -[-(-13/25)]=x but we know -(-)= + so the answer will be equal to x as x= -(-13/25)
