Review Questions

• Explain how inverse operations are used in the general strategy for solving linear equations.
  • In the general strategy for solving linear equations, inverse operations are used to isolate the variable of interest on one side of the equation. This is typically done by performing the inverse operation to undo the operations that were initially performed on the variable. For example, if the equation involves adding a number to the variable, the inverse operation of subtracting that number would be used to isolate the variable. By applying inverse operations, you can systematically eliminate the other terms in the equation, leaving only the variable on one side, which can then be solved.
• Describe the role of inverse operations in the problem-solving strategy.
  • Inverse operations are a crucial component of the problem-solving strategy. When faced with a problem that can be represented by an equation, the goal is to isolate the unknown quantity by using inverse operations. This involves identifying the operations performed on the unknown and then applying the corresponding inverse operations to undo them. By systematically applying inverse operations, you can isolate the variable or unknown and solve for its value. This skill is essential in translating real-world problems into mathematical equations and then finding the solution.
• Analyze how inverse operations are used when solving a formula for a specific variable.
  • When solving a formula for a specific variable, inverse operations are used to isolate that variable on one side of the equation. This involves identifying the operations performed on the target variable and then applying the corresponding inverse operations to undo them. For example, if the formula involves multiplying the variable by a constant, the inverse operation of dividing by that constant would be used to isolate the variable. By systematically applying inverse operations, you can rearrange the formula to solve for the desired variable, which is a crucial skill in working with and manipulating formulas in various mathematical and scientific contexts.
