Basic Mathematical Concepts] 2 1 Equation of More information. Solve rational equations with variables in the denominators.. Solving Systems of Linear Equations 3 days Investigation 2: Solving Inequalities Student Outcomes Students learn if-then moves using the addition and multiplication properties of inequality to solve inequalities and graph the solution sets on the number line. Real World Positive and Negative Numbers and Zero Student Outcomes Students use positive and negative numbers to indicate a change gain or loss in elevation with a fixed reference point, temperature,. When students In this technological age, mathematics is more important than ever. Examine the structure of the equations to determine why this is true.

Sample Problems 1, 2. Solution Sets to Simultaneous Equations Student Outcomes Students identify solutions to simultaneous equations or inequalities; they solve systems of linear equations and inequalities either algebraically or graphically. I can write a system of equations that would have one solution, no solution, or infinitely many solutions. In this chapter we discuss intuitive, graphical, and algebraic methods of solving simultaneous linear equations; that is, finding all pairs if any of numbers x, y that are solutions of both equations.
