Using the Elmination Method to Solve a System of Equations

The video tutorial covers systems of equations, focusing on the elimination or addition method. It explains how to align variables and equations, ensuring coefficients are the same for effective elimination. The tutorial provides examples of adding or subtracting equations to eliminate variables and solve for unknowns, demonstrating the process with a step-by-step approach.

What is the primary focus of the lesson after reviewing graphing systems and substitution?

• Quadratic equations

• Elimination or addition method

• Polynomial division

• Matrix multiplication

What must be aligned before applying the elimination method?

• The denominators

• The exponents

• The variables and equations

• The constants

When should you add the two equations in the elimination method?

• When one coefficient is positive and the other is negative

• When both coefficients are positive

• When both coefficients are negative

• When the coefficients are different

In the example provided, what is the value of X after applying the elimination method?

• 1

• 2

• 4

• 3

What is the solution point where the two equations intersect in the example?

• (4, 6)

• (3, 5)

• (2, 4)

• (1, 3)
