Part 1: Graph the following system of equations. What is the solution set?

2x + y = 3

x = 2y - 1

Part 2:

Solve the following system of equations by substitution. What is the solution set?

y = -2x + 3

x - 2y = - 1

Part 3:

Compare the systems of equations and their solutions in Parts 1 and 2. How are they similar? How are they different?
