E) If X=Y or cannot be established
 

1. I. X^2 = 100
      II. Y^2– 20Y + 100 = 0
 

2. I. 3X^2 +29 X +56 = 0
      II. 2Y^2 + 15Y + 25 = 0
 

3. I. 2X^2 – X – 10 = 0
      II. 2Y^2 – Y – 21 = 0
 

4. I. 3X^2 – 16X + 21 = 0
      II. 3Y^2 – 28Y + 65 = 0
 

5. I. X^2 + 3X + 2 = 0
      II. Y^2 + 5Y +6 = 0
 

6. I. X^2 = 1849
      II. Y = (1849)^1/2 
 

7. I. 2X^2 – X – 21 = 0
     II.3Y^2 + 14Y + 15 = 0
 

8. I. 3X^2 – 22 X + 40 = 0
