Solving One Step Inequalities by Adding

This guide provides a comprehensive overview of solving one-step inequalities through the concept of addition. It highlights the importance of converting subtraction into addition using its inverse and explains the Addition Property of Inequality: if a > b, then a + c > b + c, and if a < b, then a + c < b + c. Several examples are solved and graphed, including m + 3 > 6, 8 + t < 15, and -3 ≤ x + 7. A practical application, such as determining the weight limit for luggage, is also included, reinforcing these concepts with real-world context.
