Understanding One-Step Addition Inequalities

In this video, Mr. J explains how to solve one-step addition inequalities by isolating the variable using inverse operations. He demonstrates this with two examples: solving W + 7 ≥ 15 and x + 4 < 9. The video emphasizes the importance of maintaining balance in inequalities by performing the same operation on both sides. Mr. J also shows how to verify solutions by substituting values back into the inequality.

What is the primary goal when solving one-step addition inequalities?

• To multiply the variable by a constant

• To add more variables

• To isolate the variable on one side

• To find the value of the variable
