Answer:

Infinite number of solutions

Step-by-step explanation:

Write these equations in a column:

-6x+y=-21  

2x-1/3y=7

Use elimination by addition and subtraction. Start by multiplying the 2nd equation by 3, obtaining:

-6x+y=-21  

6x - y= 21

----------------

  0  - 0 = 0

There are an infinite number of solutions.  The two equations shown immediately above are multiples of one another.
