Solving Two Step Inequalities Challenge

The video tutorial explains how to solve two-step linear inequalities in one variable. It provides two examples: the first involves solving and graphing the inequality -9 + 4x > 23, and the second involves solving and graphing 46 - 5x ≤ 21. The tutorial covers the steps of undoing addition or subtraction, followed by undoing multiplication or division, and emphasizes the rule of flipping the inequality when dividing by a negative number. The video concludes with graphing the solutions on a number line.

What is the first step in solving two-step linear inequalities?

• Graph the solution

• Flip the inequality

• Undo the addition or subtraction

• Undo the multiplication or division
