Solving One-Step Inequalities

In this video, Mr. J explains how to solve one-step subtraction inequalities by isolating the variable using inverse operations. He demonstrates this process with two examples: solving y - 2 > 5 and -6 <= C - 3. The video emphasizes the importance of maintaining balance in inequalities by performing the same operation on both sides. Mr. J also shows how to check solutions by substituting values back into the inequality. The video concludes with a recap of the key steps involved in solving these types of inequalities.

What is the main goal when solving one-step subtraction inequalities?

• To divide both sides by the same number

• To isolate the variable

• To add numbers to both sides

• To multiply both sides by the same number

What operation is used to solve the inequality y - 2 > 5?

• Division

• Subtraction

• Addition

• Multiplication

If y - 2 > 5, what is the solution for y?

• y = 7

• y <= 7

• y < 7

• y > 7

Which value can be used to check the solution of y - 2 > 5?

• 8

• 5

• 7

• 6

What is the inverse operation of subtraction?

• Multiplication

• Division

• Addition

• Subtraction

In the inequality -6 <= C - 3, what operation is needed to isolate C?

• Subtract 3 from both sides

• Add 3 to both sides

• Multiply both sides by 3

• Divide both sides by 3

What is the solution for C in the inequality -6 <= C - 3?

• C >= -3

• C <= -3

• C > -3

• C < -3

Which value can be used to check the solution of -6 <= C - 3?

• 2

• 3

• 4

• 5

How can the inequality -6 <= C - 3 be rewritten for easier understanding?

• C - 3 >= -6

• C > -3

• C >= -3

• C <= -3

What is the key takeaway from solving one-step subtraction inequalities?

• Always subtract from both sides

• Use inverse operations to isolate the variable

• Divide both sides by the same number

• Multiply both sides by the same number
