Solving Multi Step Inequalities in One Variable

The video tutorial covers solving two-step and multi-step inequalities in one variable. It demonstrates solving inequalities such as 8m - 12 ≤ -36 and 9 - 3m > 21, including graphing the solution sets on a number line. The tutorial also addresses solving inequalities with variables on both sides and applying the distributive property to solve complex inequalities. Key steps include adding or subtracting terms, dividing by coefficients, and reversing inequality signs when dividing by negative numbers.

What is the first step in solving the inequality 8m - 12 ≤ -36?

• Divide both sides by 8

• Multiply both sides by 8

• Subtract 12 from both sides

• Add 12 to both sides

How do you solve an inequality with variables on both sides?

• Apply the distributive property first

• Isolate variables on one side first

• None of the above

• Combine like terms first
