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?

• Substitute the expression into the other equation

• Multiply both equations by a constant

• Solve one of the equations for one of the variables

• Check the solution

In the given system of equations, what is the expression for P?

• P = N + 5

• P = 1.5N

• P = 2N

• P = 3N

What operation is performed to isolate the variable N in the equation -5 = -0.5N?

• Subtract 0.5 from both sides

• Divide both sides by -0.5

• Multiply both sides by -0.5

• Add 5 to both sides

After finding N = 10, what is the next step to find P?

• Substitute N = 10 into the second equation

• Substitute N = 10 into the first equation

• Check the solution

• Multiply N by 5

What is the value of P when N = 10?

• P = 15

• P = 10

• P = 20

• P = 25

How do you verify the solution of the system of equations?

• By substituting the values into a new equation

• By solving another system of equations

• By checking if the values satisfy both original equations

• By graphing the equations

What is the final conclusion about the value of N in the system of equations?

• N = 5

• N = 10

• N = 15

• N = 20
