Solving Equations with Variables on Both Sides (1.3 Big Ideas Math - Algebra 1)
Mr. G Math・2 minutes read
Linear equations with variables on both sides can be solved by simplifying each side, using inverse operations to isolate the variable, and verifying the solution. No solution and infinitely many solutions can also arise in linear equations, as demonstrated through examples and real-life problems involving rates and distances.
Insights
- When solving linear equations with variables on both sides, simplify each side by combining like terms or using the distributive property, then use inverse operations to isolate the variable on one side and constants on the other side.
- Introduce the concepts of no solution and infinitely many solutions in linear equations, where a false statement indicates no solution and identical sides signify infinitely many solutions.
