Introduction to Solving a System of Linear Equations Using Elimination

What defines like variable terms?

• They have the same variables and powers.

• They have different coefficients.

• They have different variables and powers.

• They have the same coefficients.

Which of the following pairs are like terms with the same coefficient?

• 6X and 7X

• 3X and 3Y

• 4X and 4X

• 5X and 5Y

What should you do if like variable terms have opposite coefficients?

• Add the equations.

• Multiply the equations.

• Divide the equations.

• Subtract the equations.

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

• Check the solution.

• Solve for the remaining variable.

• Identify like terms with same or opposite coefficients.

• Write the solution as an ordered pair.

In the example problem, what is the solution for X when the equations are added?

• X = 0

• X = 1

• X = 2

• X = 3

What is the ordered pair solution for the example problem?

• (0, 2)

• (1, 5)

• (2, 3)

• (3, 4)

When solving a system of equations, what is the final step?

• Identify like terms.

• Subtract the equations.

• Check the solution.

• Add the equations.

In the practice problem, what is the value of Y when X is solved?

• Y = 1

• Y = 2

• Y = 3

• Y = 4

What is the ordered pair solution for the practice problem?

• (4, 5)

• (3, 4)

• (2, 3)

• (1, 2)

What should you do if like variable terms have the same coefficient?

• Subtract the equations.

• Multiply the equations.

• Divide the equations.

• Add the equations.
