Final answer:
The equation has no solution.
Step-by-step explanation:
The equation -x + (-3) = x + 3 can be solved using algebra tiles.
When we represent -x using algebra tiles, we use a negative single variable tile. And when we represent (-3), we use three negative unit tiles. Similarly, when we represent x, we use a positive single variable tile. And when we represent (3), we use three positive unit tiles.
Now, if we add the tiles on both sides of the equation, we get 0 = 6. This means that there is no value for x that satisfies the equation.
