To solve the equation \(2x + 1 = 4\), follow these steps:

1. **Isolate the term containing \(x\)**:
   \[
   2x + 1 = 4
   \]
   Subtract 1 from both sides:
   \[
   2x + 1 - 1 = 4 - 1
   \]
   Simplifies to:
   \[
   2x = 3
   \]

2. **Solve for \(x\)**:
   \[
   2x = 3
   \]
   Divide both sides by 2:
   \[
   x = \frac{3}{2}
   \]

So, the solution is \(x = \frac{3}{2}\) or \(x = 1.5\).
