Question 1 
  
Which of the following is the solution to system
3x + 4y = 7 
x + 2y = 2 
Answer 
  
 (x = 6, y = -2) 
  
 (x = 5, y = -2) 
  
 (x = 4, y = -1/2) 
  
 (x = 3, y = -1/2)
X= 3 , y= -1/2
Question 2 
  
Determine whether the system of linear equations has one and only one solution, 
infinitely many solutions, or no solution. 
2x - 3y = 2 
6x - 9y = 8 
Answer 
  
 one solution 
  
 infinitely many solutions 
  
 no solution 
  
 can not tell 
10 points     
No solution
Question 3
