B. Solve systems of two linear equations in two variables algebraically, and estimate solutions by graphing the equations. Solve simple cases by inspection. For example, 3x + 2y = 5 and 3x + 2y = 6 have no solution because 3x + 2y cannot simultaneously be 5 and 6.
How to Solve a System of Equations
Watch the video with Rich Eisen racing against Julio Jones. Use the worksheet to guide you through. Stop the video when Rich and Julio are in the same place. Which yard line and after how many seconds does Julio catch Rich?



Identify how many solutions by inspection.This will help you with the IXL on finding the number of solutions to a system of equations.
It is all about the SLOPE! Look at the slopes first and that will give you an idea about how the lines are interacting with each other.
