XEI 506: Solve first-degree inequalities that do not require reversing the inequality sign* XEI 601: Write expressions, equations, and inequalities for common algebra settings Solving One-Step Linear Inequalities
Linear Inequalities • Solving linear inequalities is similar to solving equations, except you have an inequality sign instead of an equal sign. • You will follow the same steps as if you would solve an equation.
Solve a Linear Inequality x + 3 > 9 – 3 – 3 x > 6 Now graph it! .
Solve a Linear Inequality -5 + x < -1 + 5 +5 x < 4 Now graph it!
