Help. PLEASE...

Answer 1

Explanation:

Hello,

`-x\geq -4\\ \\<=>0=-x+x\geq -4+x\\\\<=>4+0=4\geq -4+x+4=x`

Then, we find that

`\Large \boxed{\sf \bf x\leq 4}`

For instance if x = 0

-x = 0 and the following is true and equivalent

`0\geq -4`

`0\leq 4`

If x = 2

-x = -2 and the following is true and equivalent

`-2\geq -4\\ \\2\leq 4`

Thanks
