Answer 2

To solve the compound inequality -5 < 9 + 2x < 17, you can break it down into two separate inequalities and solve each of them individually.

1. The first inequality is: -5 < 9 + 2x.

   First, subtract 9 from both sides: -5 - 9 < 9 + 2x - 9 -14 < 2x

   Now, divide by 2 (since it's a positive number, we don't need to reverse the inequality symbol): -14 / 2 < 2x / 2 -7 < x

2. The second inequality is: 9 + 2x < 17.

   First, subtract 9 from both sides: 9 + 2x - 9 < 17 - 9 2x < 8

   Now, divide by 2 (since it's a positive number, we don't need to reverse the inequality symbol): 2x / 2 < 8 / 2 x < 4

So the solution to the compound inequality -5 < 9 + 2x < 17 is -7 < x < 4.
