About the Lesson
This lesson involves understanding what it means for an equation to be balanced in the process of solving linear equations with one variable.
As a result, students will:
- Examine the graphs of the two separate expressions from a linear equation with one variable and then noticing their point of intersection as a solution to the original equation.
- Find the solution(s) of a linear equation by transforming it into equivalent equations in simpler forms using the idea of balancing equations and the properties of equality.
- Determine if a linear equation has one, infinitely many, or no solutions by examining the final equivalent equation found.
