To solve the equation $3x + 4 = -4 + 3x$, follow these steps:

1. Start by subtracting $3x$ from both sides to eliminate the $3x$ terms: $3x + 4 - 3x = -4 + 3x - 3x$ This simplifies to: $4 = -4$

2. This results in a false statement ($4 \neq -4$). Therefore, the equation has no solution.

This is an inconsistent equation, meaning there is no value of $x$ that satisfies it.
