Answer:
Step-by-step explanation:
Hello,
[tex]-x\geq -4\\ \\<=>0=-x+x\geq -4+x\\\\<=>4+0=4\geq -4+x+4=x[/tex]
Then, we find that
[tex]\Large \boxed{\sf \bf x\leq 4}[/tex]
For instance if x = 0
-x = 0 and the following is true and equivalent
[tex]0\geq -4[/tex]
[tex]0\leq 4[/tex]
If x = 2
-x = -2 and the following is true and equivalent
[tex]-2\geq -4\\ \\2\leq 4[/tex]
Thanks
