### Knowledge

Students know:
• how to solve one and two step equations with one variable.
• Write linear equations given real-world contexts.
• That a solution to an equation can represent a real-world quantity.

### Skills

Students are able to:
• apply the distributive property and combine like terms to simplify an equation.
• Recognize a solution as representing one solution, no solution, or infinite solutions.
• Analyze and solve a real-world problem and write an appropriate equation for it that leads to a solution that can be explained within the context of the problem.

### Understanding

Students understand that:
• equations can now have more than one solution in given real-world scenarios.
• The distributive property and combining like terms are essential to simplifying an equation. therefore making it easier to solve.

### Vocabulary

• one solution
• no solution
• Infinitely many solutions
• like terms
• Distributive property
