(1) $$-1\leq{x}\leq{1}$$

X could be 1 or -1...................Answer is No

X could be 0...........................Answer is yes

Insufficient

(2) If x is the units digit of a number, that number is divisible by both 5 and 10.

As long as a number is divisible by 10 so its unit digit must be 0. Then, x is 0.. I means x is even

Sufficient

My solution :
1, x >/ -1 x</ 1
x = -1,0,1
From this only even value of x = 0
2, x = units digit
x = 0 which is divisible by 5 and 10

Why am I wrong?
I missing some basic DS strategy? Pls help. thanks

-1≤x≤1 means x can have value of -1, 0 and 1 and not just 0.( symbol ≤ means greater or equal to)
-1<x<1 means x has value greater than -1 but less than 1(not equal to) the only value is 0 In this case statement is sufficient.
