Solve Systems Using Elimination Method for Special Cases

• (2, -2)
• (2, 2)
• (-2, 2)
• (-2, -2)

Solve by elimination:
9x-4y=7

x-4y=-17

• (-1,5)

• (-7,5)

• (7,5)

• (3,5)

Solve the system by elimination.  

−7x + 6y = 29
10x + y = 16 

• (1,6) 

• (−1,−3) 

•  (−3, −1) 

• (−1, 3) 

Solve the system by elimination. 
−4x − 4y = 0
4x + 4y = 0 

• (−6, −4) 

• Infinite number of solutions  

• (−6, 10) 

• (6, 4) 

Solve using Elimination Method:

x - y = 11

2x + y = 19

• (10,-1)

• (-1,10)

• (3,-4)

• (6,7)

what is the variable that willl be "eliminated"?

5x - 4y = 11

5x + 4y = -14

• x variable

• y variables

• both variables

Solve using Elimination Method:

4x + 9y = 28

-4x - y = -28

• (-7,0)

• (6,0)

• (-6,0)

• (7,0)

• (6,7)

x = -3y - 17

2x + 3y = -7

• (1, -2)

• (3, 0)

• (-5, -2)

• (10 , -9)

• (10, 2)
