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
