• Finding the speed of a car

• Determining where supply meets demand

• Balancing chemical equations

In algebra classes, how are systems of equations typically represented?

• With algebra tiles

• Using graphs

• Through word problems

• By drawing circles

What is the first step in solving a system of equations using substitution?

• Multiplying the equations

• Graphing the equations

• Isolating one of the variables

• Adding the equations together

When isolating 'y', what operation is performed on the left side of the equation?

• Multiplying by two

• Adding two negative x's

• Adding two positive x's

• Subtracting two y's

After isolating 'y', what is the next step in solving the system of equations?

• Add the equations together

• Substitute 'y' into the second equation

• Graph the equation

• Divide both sides by two

What happens to the positive and negative x's on the right side of the equation?

• They cancel each other out

• They are multiplied

• They are divided

• They are added together

What is the value of 'x' after simplification?

• x = 3

• x = 0

• x = 1

• x = 2

How do you find the value of 'y' after determining 'x'?

• Multiply 'x' by 2

• Divide 'x' by 2

• Add 'x' and 'y' together

• Substitute 'x' into the original equation for 'y'

What is the final value of 'y' in the solved system of equations?

• y = 2

• y = 0

• y = 1

• y = 3

What method is used to solve the system of equations in the video?
