\[-x - 5 \le-2 \]
\[2x >-6 \]
\[x - 4 <-7 \]
\[6 + x \le3 \]
OpenStudy (evansanchez):
is that better?
OpenStudy (will.h):
Much. Good work
OpenStudy (will.h):
So we have to solve for x for each inequality above
OpenStudy (will.h):
1- x bigger than or equal to -3
That means it matches with the 3rd line in the picture.
(I solved the inequality the same way we solve equations)

2-
x > -3
That matches with 1st line
OpenStudy (evansanchez):
which inequality is that?
OpenStudy (will.h):
The 2nd.
OpenStudy (will.h):
2x > -6 this one
OpenStudy (will.h):
Make sense so far?

Now this inequality
X - 4 < -7
We solve for x 1st
X < -3
This matches with the 2nd line
OpenStudy (will.h):
6 + x Less than or equal to 3
Solve for x
X less than or equal to -3
That matches with the 4th line
OpenStudy (evansanchez):
okay, got it!
OpenStudy (will.h):
Do you understand what I did?
OpenStudy (evansanchez):
yes!
