GCSE Secondary Maths Age 13-17 - Algebra: Inequality - Explained

The video tutorial explains how to solve inequalities using methods similar to solving equations. It covers the process of solving the inequality 6y + 5 > 8, including subtracting and dividing steps. The tutorial also discusses boundary points in inequalities, explaining how open and closed circles represent values that are not included or included in the solution set.

What is the first step in solving the inequality 6y + 5 > 8?

• Divide both sides by 6

• Multiply both sides by 6

• Subtract 5 from both sides

• Add 5 to both sides

After subtracting 5 from both sides in the inequality 6y + 5 > 8, what is the next step?

• Add 3 to both sides

• Multiply both sides by 3

• Subtract 3 from both sides

• Divide both sides by 6

Which of the following is an acceptable form of the solution for the inequality 6y + 5 > 8?

• y ≥ 3/6

• y = 3/6

• y < 3/6

• y > 3/6

What does an unfilled circle on a number line indicate about the value of X?

• X can be equal to the value

• X must be less than the value

• X must be greater than the value

• X can be any value

If a circle is filled in on a number line, what does it mean for the value of X?

• X cannot be equal to the value

• X must be less than the value

• X can be equal to the value

• X must be greater than the value
