Question 134032: Identify the system of equations which has no solution.
a. -x=3y+1
x=3y-1

b. x-2y=-6
2x=4y-12
c. x=2y-1
2x=4y

You can put this solution on YOUR website!
There is no solution for b. This is becuase the two equations listed in B are, in fact the same equation.
x+-+2y+=+-6
x+=+2y+-+6 multiply by 2
2x+=+4y+-+12
Which is the second equation given. There are two variables and only one eqaution, so you can't solve this one.
