**Solve an Equation**Place tiles equal to the expression to the left of the = in the left
workspace. Place tiles equal to the expression to the right of the = in
the right workspace. For example, if the expression is 3*x*– 2, place 3 green *x* tiles and 2 red *1* tiles
in one half of the workspace. You will need to flip the tiles to get
the red inverse tiles. Check your model to move on to the next step.

To solve the problem, arrange tiles so only a single green tile
remains in one half of the workspace. Remember only equal values can be
removed from both sides, such as a yellow tile from the left and a
yellow tile from the right. To "move" a tile, first add the inverse
value to both sides. If you want to move a red rectangle, add a yellow
rectangle to both sides. Then you can remove the zero pair from one
side.

Try solving several problems in this manner.
