Answer 8

does any body know how to do this prob.\[1<2y+5\le9\]

Answer 9

That's ok, Chloe!

ok for this secton one, you start by subtracting 5 from all the parts.

\[1-5<2y+5-5<9-5\]

\[-4<2y<4\]

Answer 10

Then you aren't quite done yet - you have a 2y in the middle and you need to have JUST a y, so you divide all three parts by 2.

Answer 11

\[-4/2<2y/2 <4/2\]

-2<y<2
