Step-by-step explanation:
Let us try to solve each of the system of equations one by one.
1. 

This gives

which has no solutions.
2. 

let us write them in y-intercept form


and equate them

this gives
and

This equation has solutions.
3. 

Notice that the second equation is just the first equation multiplied by 2, or

<em>so these are identical equations and therefore</em> this system has infinitely many solutions.
Thus we have
1. No Solution
2. One solution
3. Infinitely many solutions
