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