OpenStudy (scarlettfarra2000):
Any idea how to do this?
OpenStudy (atrineas):
Not at all I feel so dumb
OpenStudy (scarlettfarra2000):
Okay and you're not dumb

the answer for that question was -18 because of how the -18 needed to go into both terms to get the answer to the inequality
OpenStudy (odysseus_12345):
\[3(x-6)-4x \ge-3\]
OpenStudy (atrineas):
It was wrong and I'm on the final check again
OpenStudy (atrineas):
@TheSmartOne help please if you have the time
TheSmartOne (thesmartone):
Distribute the 3 first
Hint: a(b - c) = ab - ac

3x-18?
TheSmartOne (thesmartone):
correct, now we have
\(3x - 18 - 4x \ge -3\)
What is 3x - 4x = ?
OpenStudy (atrineas):
-x?
TheSmartOne (thesmartone):
corect, now we have
\(-18 - x \ge - 3\)
Do you like to deal with negative numbers? :P
OpenStudy (atrineas):
What do I do now?

Add x to both sides
Add 3 to both sides
OpenStudy (atrineas):
-18+3>x?
TheSmartOne (thesmartone):
It's actually \(\ge\) not >
but continue to simplify the left hand side
-18 + 3 = ?
OpenStudy (atrineas):
I don't know how to do that symbol and -15
TheSmartOne (thesmartone):
`\(\ge\)`
and correct

Now you have
-15 \(\ge\) x
That's the same thing as
x \(\le\) -15
`\(\le\)`
OpenStudy (atrineas):
ok and that would be the answer? or is there more
TheSmartOne (thesmartone):
That's all :)
OpenStudy (atrineas):
Thank you so much ^~^
TheSmartOne (thesmartone):
Anytime! (:
