How yo combine like terms using algebra tiles?

To combine like terms using algebra tiles, first, represent each term with the appropriate tiles: use large tiles for positive and negative whole numbers and smaller tiles for variables (like 'x'). Arrange the tiles on a flat surface, grouping together tiles of the same type (e.g., all 'x' tiles together and all constant tiles together). Count the total number of each tile type to find the simplified expression, combining positive and negative tiles to determine the final sum.
