any answer choices?

To solve for 'w' we must divide -6 to both sides..can you do that? @victoriairvinxxx
OpenStudy (anonymous):
nooooooooooooo
OpenStudy (anonymous):
w>14
w<-14
w>-14
w<14
OpenStudy (igreen):
\(\sf -6w < 84\)
\(\sf \dfrac{-6w}{-6} < \dfrac{84}{-6}\)
\(\sf \dfrac{\cancel{-6}w}{\cancel{-6}} < \dfrac{84}{-6}\)
The -6's on the left cancel out, leaving us with:
\(\sf w > \dfrac{84}{-6}\)
Remember, we switch the sign when dividing or multiplying by a negative number.
Now all you have to do is divide 84 / -6.
