In today’s lesson, we continue with linear equations, focusing on forming and solving them through examples involving “mysterious numbers” in word problems. Students learn to think of a number and perform operations such as addition, subtraction, multiplication, or division to uncover the original number used in the problem. The lesson emphasizes balancing equations, meaning that any operation performed on one side must also be done on the other side to maintain equality. As students work through easy examples, they will advance to more complex problems involving multiple operations.
