To solve the equation \( 30k + 1 = 4 \), we will start by isolating \( k \).
1. Subtract 1 from both sides of the equation:
\[
30k + 1 - 1 = 4 - 1
\]
which simplifies to:
\[
30k = 3
\]
2. Next, divide both sides by 30:
\[
k = \frac{3}{30}
\]
3. Simplify the fraction:
\[
k = \frac{1}{10}
\]
Therefore, the solution for \( k \) is \( \frac{1}{10} \).
