This year we began learning about solving Multi-step equations and inequalities. We have already learned how to solve two-step equations, how to solve equations having Like terms and parentheses and how to solve equations with variables on both sides. Today (November 10 2011) we are going to learn how to solve inequalities using addition or subtraction.
3.1 Includes many types of solving, solving two step equations. Solving two- step Equations .... Using Subtraction and division to solve.. Using Addition and Multiplication to solve. Using an Equation with Negative Coefficients. The last one is Writing and Solving a two-step Equation
Using Subtraction and Division to solve
Using Addition and Multiplication to solve
Solving an Equation with Negative Coefficients
