Write the algebraic expression modeled by the tiles and simplify it by combining like terms.
x-6
Let's examine each of the given algebra tiles and what they represent.
We have one tile that represents x, and six tiles whose value is -1. By adding these, we can create an algebraic expression modeled by the tiles. x+( -1)+( -1)+( -1)+( -1)+( -1)+( -1) Finally, we will combine like terms to simplify the above expression. x - 6
