To solve the equation \( 4u + 13 = 43 \), we need to isolate \( u \). Here are the steps:

1. **Subtract 13 from both sides**:
   \[
   4u + 13 - 13 = 43 - 13
   \]
   \[
   4u = 30
   \]

2. **Divide both sides by 4**:
   \[
   \frac{4u}{4} = \frac{30}{4}
   \]
   \[
   u = \frac{30}{4}
   \]
   \[
   u = 7.5
   \]

So, the solution is \( u = 7.5 \).
