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

This is because the absolute value of any expression is always non-negative (i.e., $|A| \geq 0$ for any real number $A$). Since the right-hand side of the equation is a negative number (-3), there is no value of $x$ that would make the absolute value equal to -3.

Therefore, the equation is inconsistent, and no real solutions exist.

Tip: Always remember that absolute values represent distance and can never be negative.
