Answer
The solution set is {-7, 7}.
Solution
Part (a)
|b| = 7 means b is either 7 or -7.
Thus, the solution set is {-7, 7}.

Bonus Knowledge
For the equation \( |b|=7 \), this means that \( b \) can take two values: \( b = 7 \) or \( b = -7 \). Therefore, the solution set is \( \{ -7, 7 \} \). For the inequality \( |b|<7 \), this means \( b \) lies strictly between -7 and 7, not including those endpoints. Hence, in interval notation, the solution set is \( (-7, 7) \). For the inequality \( |b|>7 \), this signifies that \( b \) is either less than -7 or greater than 7, which means it is outside the range of -7 and 7. In interval notation, this gives us the solution set \( (-\infty, -7) \cup (7, \infty) \).
