Systems by Elimination: Level 1/2

Solve the following system by using elimination:

3x - 5y = 8

2x + 5y = -3

• (1, 5)

• (1, -1)

• (-1, -1)

Solve using Elimination. 
 4x + 8y =  20
-4x + 2y = -30

• (-7,1)
• (2,-5)
• (-2,5)
• (7,-1)

10x-8y=-30

-10x+9y=25

Which variable will be eliminated?

• the x

• the y

Solve using elimination.

-2x+2y=0

2x+6y=-16

• (-2,-9)

• (-2,-2)

• no solution

• infinitely many solutions

 $3x-2y=12$  

 $2x+2y=-2$  

What variable will eliminate in the system? 

• x

• y

• both

• neither

Solve for x:

  $\ x-y=-19$  
 $5x+y\ =\ 1$  

•  $x=-4$  

•  $x=-3$  

•  $x=5$  

•  $x=6$  

Solve the system by elimination:
 $x+y=6$  
 $6x-y=1$  

• (3, 3)

• (1, 5)

• (1, 3)

• (7, -1)

Solve the system by elimination: 
 $x+2y=-4$   
 $-x-3y=6$  

• (-2, -1)

• (2, -3)

• (4, -4)

• (-4, 0)

Solve by elimination:
 $-9x-4y=-20$  
 $5x\ +\ 4y\ =\ 4$  

• (-4,4)

• (4,4)

• (4,-4)

• (-4,-4)

Solve the system:
 $3x+1y=19$  
 $2x-1y=6$  

• (5, 14)

• (4, 5)

• (5, 4)

• (14, 5)
