Elimination Method for Linear Equations

The video tutorial explains the elimination method for solving linear equations with two variables. It begins by introducing the method and the need to make the coefficients of either variable equal. The tutorial demonstrates solving for Y by making the X coefficients equal and then solving for X by making the Y coefficients equal. The instructor emphasizes the ease of the elimination method compared to others and concludes by encouraging viewers to subscribe.

What is the first step in the elimination method for solving linear equations?

• Subtract the equations directly

• Make the coefficients of one variable the same

• Solve for one variable first

• Add the equations directly

When making the coefficients of x the same, what operation is performed to eliminate x?

• Addition

• Subtraction

• Division

• Multiplication

What happens to the signs of the second equation when subtracting to eliminate x?

• They remain the same

• They are reversed

• They are doubled

• They are halved

After finding the value of y, what is the next step?

• Multiply both equations by a constant

• Substitute y into one of the original equations

• Add the equations again

• Solve for z

What is the value of y when the coefficients of x are made the same and subtracted?

• 0

• 1

• 2

• 3

How do you make the coefficients of y the same in the elimination method?

• Subtract a constant from both equations

• Divide both equations by a common factor

• Multiply one or both equations by a suitable number

• Add a constant to both equations

What is the result when the coefficients of y are made the same and the equations are added?

• The equations become identical

• The x terms are eliminated

• The solution is found directly

• The y terms are eliminated
