Consider the Equation Mat at right.

Refer to the Math Notes box below for help.

Write the original equation represented.

Count the number of

-tiles and unit tiles on each side of the equation, then turn that into an equation.Simplify the tiles on the mat as much as possible. What value of

will make the two expressions equal?Remove matching sets of tiles from each side.

Now you are left with

-tiles on the left andunit tiles on the right. Divide each side by to find the value of .
