To solve the equation \( 147 = b - (-12) \), simplify it step by step.

1. The double negative simplifies to a positive:
   \[
   147 = b + 12
   \]

2. To isolate \( b \), subtract 12 from both sides:
   \[
   147 - 12 = b
   \]
   \[
   135 = b
   \]

So, the value of \( b \) is \( 135 \).

4. Solve for \( b \) in \( b - (-5) = 45 \).
5. If \( b - (-3) = 100 \), what is the value of \( b \)?
