To solve the equation \( x - (-1) = 4 \), follow these steps:

1. Simplify the left side of the equation by noting that subtracting a negative number is the same as adding:
   \[
   x + 1 = 4
   \]
2. Subtract 1 from both sides to isolate \( x \):
   \[
   x = 4 - 1
   \]
3. Simplify:
   \[
   x = 3
   \]

Thus, the solution is \( x = 3 \).
