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.
