Answer
a) $\lt3$
b) $\gt3$
Work Step by Step
a) Picture a time line from -3 to 3. There are 3 units on each side of the zero mark, from that zero point to the edges. Staying in that frame, we get $ |x| \lt3$
b) Picture a time line from negative infinity to infinity. Jumping 3 units on each side of the zero mark gives us |x| $\gt$ 3
