Let's solve the equation step by step:

The equation is:

$\frac{1}{2}\left|2x+1\right|=\left|-4+1\right|$

1. Simplify the absolute value on the right side:

$\left|-4 + 1\right| = \left|-3\right| = 3$

So the equation becomes:

$\frac{1}{2}\left|2x + 1\right| = 3$

2. Multiply both sides by 2 to eliminate the fraction:

$\left|2x + 1\right| = 6$

3. Solve the absolute value equation:

The equation $\left|2x + 1\right| = 6$ can be split into two cases:

Case 1: $2x + 1 = 6$

$2x = 6 - 1$ $2x = 5$ $x = \frac{5}{2}$

Case 2: $2x + 1 = -6$

$2x = -6 - 1$ $2x = -7$ $x = \frac{-7}{2}$

Thus, the solutions are:

$x = \frac{5}{2} \quad \text{or} \quad x = \frac{-7}{2}$

Final Answer:

$x = \frac{5}{2} \quad \text{or} \quad x = \frac{-7}{2}$
