Before you look at example 3 I strongly encourage you to review multiplication and division of fractions. Solve the following two-step equations that have addition and multiplication in them. Addition x y.
Lastly solve any addition or subtraction.
6 6 12 and 2 x 6 12 Hand out six paper plates two dice 36 linker cubes and a sheet of paper to each pair of students. Then use the multiplication principle and divide both sides of the equation by 3 to get x 7. Once students have learned how to write equations translate sentences into equations translate equations into sentences and solve one-step equations using addition and subtraction they are now ready to move onto solving simple equations using multiplication or division. Both parenthesis have been simplified.
