Algebra tiles can be used to solve addition or subtraction equations by representing each term in the equation with an algebra tile. For example, if the equation is 3x + 5 = 10, the 3x can be represented with three x-tiles and the 5 can be represented with five unit tiles. To solve the equation, the tiles can be moved around until the equation is balanced. In this case, the three x-tiles can be moved to the right side of the equation and the five unit tiles can be moved to the left side of the equation. This will result in 3x = 5, which can be solved by dividing both sides by 3 to get x = 5/3.
