The equation $|3a + 2| = -4$ has no solution.

This is because the absolute value of any expression is always non-negative (i.e., greater than or equal to zero). Therefore, it is impossible for the absolute value of $3a + 2$ to be equal to a negative number like $-4$.

Thus, there is no value of $a$ that satisfies the equation.
