To solve the equation \(30k + 1 = 4\), follow these steps:
1. Subtract 1 from both sides of the equation:
\[
30k + 1 - 1 = 4 - 1
\]
Simplifying this gives:
\[
30k = 3
\]
2. Now, divide both sides by 30:
\[
k = \frac{3}{30}
\]
3. Simplify \( \frac{3}{30} \):
\[
k = \frac{1}{10}
\]
So, the solution for \(k\) is \( \frac{1}{10} \).
