This system have $\infty$ $oo$ solutions because you have the equations of two coincident lines!

Explanation:

The second equation is equal to the first multiplied by $2$ $2$ ! So basically they are the same two lines one on top of the other.
Your two lines share an $\infty$ $oo$ number of common points and so they also share an $\infty$ $oo$ number of solutions!
