Solving 2 Step Inequalities

The video tutorial covers solving inequalities, starting with isolating variables and using inverse operations. It explains how to represent inequalities on a number line and handle rational numbers. The tutorial also addresses solving inequalities with negative coefficients, emphasizing the need to flip the inequality sign when dividing or multiplying by a negative number.

Why is it suggested to circle the variable when solving inequalities?

• To make the equation look neat

• To make the variable look important

• To confuse the solver

• To isolate the variable and focus on it
