equations using division
doing this algebraically
Ex.
7y=63(first thing you want to do is to leave the variable in one side alone.)

7y=63
7......7 (you need to divide it now)

y=9


doing it with algebra tiles
Ex.


1) it is 2x=-4
2) regroup the tiles to display the value for one variable
3)the answer is x=2


just look at this site for more info

    Neat Christian!

    I especially like your drawings. Did you just use paint?

    Maybe you could make a key for people that have never seen algetiles before. What does a white box represent? How about a red one?

    Keep up the great work!
