Classify each set of equations whether it has exactly one solution, no solution or infinitely many solutions. 1.) x + 2y = 7
x - y = 4

2.) x - y = 4
3x - y = 2

3.) x + y = 2
x + y = 4

4.) x - y = 3
4x - 4y = 12

5.) 2x + y = 3
4x + 2y = 6

6.) x + 2y = 6
x = 10 - 2y

7.) 2y = 4x - 6
3x - y = 2

8.) 2x - 3y = -3
y= 2/3x - 2

9.) 4x = y - 6
4y = 3x - 5

10.) 6x = 9y + 12
2x - 3y = 4

11.) y= 3/2x + 1/2
3x - 2y = - 1/2

12.) 3x + 7 = -5y
5y - 7 = -3x

13.) x - y = 3
2x - 1/2y = -6

14.) 3x = 6y - 9
3x = -6y + 9

15.) x + 2y = 6
2x - y = 6
