**Student Outcomes**

1. Students transform equations into simpler forms using the distributive property.

2. Students learn that not every linear equation has a solution.

**Lesson Questions / Review**

- We know how to transform equations into simpler forms using the distributive property.

- We now know that there are some equations that do not have solutions.

**Lesson Summary**

**Student Outcomes**

1. Students know the conditions for which a linear equation will have a unique solution, no solution, or infinitely many solutions.

**Lesson Questions / Review**

- We know that equations will either have a unique solution, no solution, or infinitely many solutions.

- We know that equations with no solution will, after being simplified on both sides, have coefficients of that are the same on both sides of the equal sign and constants that are different.

- We know that equations with infinitely many solutions will, after being simplified on both sides, have coefficients x of and constants that are the same on both sides of the equal sign.

**Lesson Summary**

Use the following to reinforce the concept of one, no, or infinite solutions of a linear equation.
