^{What is the solution?} 

• 1
• -2
• (1, 2)
• (1, -1)

Solve the system of equations:
y=2x
x + y = 9

• (6, 3)
• (3, 6)
• (-3, -6)
• no solution

Solve the system by substitution. 
-2x - 2y = 16
y = -8

• (0, -8)
• (-8, 0)
• (-16, -8)
• (-16, -8)

Solve the system by substitution. 
y = 2x − 11 
2x − 8y = 4 

•  (6, 1)
• (6, −4)
• (6, −1)
• Infinite number of solutions  

Solve the system by substitution. 
3x − 2y = 7 
y = 2x − 7 

• No solution 
•  (7, 7)  
•  (−7, −7)  
•  (−7, −3)
