Literal Equations Explained | Solve for a Variable Step-by-Step

Rearranging Formulas: Solve for a Variable Using Inverse Operations (Circle Circumference & Area) The lesson’s target is to rearrange formulas to isolate a specific variable using inverse operations, aligned to a Common Core algebra standard. Using the circumference formula C = 2πr, the teacher models isolating r by dividing both sides by 2π and works a numeric example with C = 314 and π ≈ 3.14 to find r = 50, emphasizing checking whether the result makes sense and clarifying that 314 was a chosen example value, not π. Students review steps for isolating variables and key inverse operations (addition/subtraction, multiplication/division, squaring/square rooting). The class then isolates r in the area formula A = πr² by dividing by π and then square rooting. An exit ticket solves for x in y = ax².
