How do you solve and graph linear inequalities in one variable? This video will show you how to graph solution sets of inequalities in one variable. The video also discusses the effect of performing a given operation on each side of the inequality on the sense of the original inequality. You will learn when to reverse the order of the inequality and in which operation.
How do you solve linear equations with a variable on both sides? This video will show how to use linear equations with a variable on both sides to solve a data plan problem. The video also models how to solve equations that have no solution, one solution, and infinitely many solutions.
