CHECKLIST for Solving a System of Equations | 8.EE.C.8

The video tutorial explains how to solve a system of equations using a five-step checklist. It begins with solving one equation for a variable, substituting it into the other equation, solving the resulting equation, and then finding the other variable. Finally, it checks the solution to ensure it satisfies both equations. The tutorial uses a specific example to demonstrate each step, encouraging viewers to pause and try solving it themselves.

What is the first step in the checklist for solving a system of equations?

Explain how to substitute an expression from one equation into another.

What do you do in Step 3 of the checklist?

Describe the process of solving for N in the given equations.

What is the final value of P after substituting N into the equation?

How do you check your work after solving the equations?

What value of N makes the system of equations true?
