Solving a two step inequality

The video tutorial covers solving inequalities involving parentheses and two-step operations. It explains how to handle numbers outside parentheses, solve inequalities by undoing addition and multiplication, and create a number line to visualize solutions. The tutorial also discusses when to switch inequality signs, emphasizing the importance of dividing or multiplying by negative numbers.

What is the first step to solve the inequality 9X + 63 ≥ 198?

• Divide both sides by 9

• Add 63 to both sides

• Subtract 63 from both sides

• Multiply both sides by 9

After subtracting 63 from both sides, what is the next step to solve the inequality?

• Divide both sides by 9

• Subtract 9 from both sides

• Add 9 to both sides

• Multiply both sides by 9

What is the solution to the inequality 9X + 63 ≥ 198?

• X > 15

• X < 15

• X ≤ 15

• X ≥ 15

When representing the solution X ≥ 15 on a number line, what should you do at the point 15?

• Draw an arrow to the right

• Leave it open

• Draw a filled circle

• Draw an arrow to the left

When do you need to switch the direction of the inequality sign?

• When multiplying or dividing by a positive number

• When adding a positive number

• When subtracting a positive number

• When multiplying or dividing by a negative number
