Systems of Equations Elimination Test

Julie is asked to solve the system below by elimination. Which of the following steps would be the BEST way to begin?

• 
• 
• 
• 

Solve the system of linear equations:

-4x + y = 6

-5x - y = 21

Solve using Elimination Method:

4x+ 9y = 28

-4x -y = -28

• (-7,0)

• (6,0)

• (-6,0)

• (7,0)

• (6,7)

Which method uses the following rule: 
Align the like terms  

• Graphing
• Elimination
• Subtraction 

The solution of a system of linear equations is...

• the y-intercept (b)
• the intersection of the two equations on a graph
• the second equations' answers
• the slope (m)

Solve the system of linear equations 
5x - 3y = -36
2x + 3y = 15

• (-3, 7)
• (-3, -5)
• (7, -3)
• (-3, 0)

Solve the system of linear equations:

-4x - 6y = 6

4x + 6y = -4

• no solution

• (2,0)

• (-4,0)

• (0,0)

What variable do you eliminate?

4x + 8y = 20

−4x + 2y = −30

• X because they have opposite signs

• Y because they have opposite signs

• Both variables will eliminate

Which of the following are ways to solve systems of equations? 

• Graphing
• Substitution
• Elimination
• All of the above

How do you write an ordered pair?

• (X,X)
• (Y,X)
• (X,Y)
• (Y,Y)
