Step-by-step explanation:
The number of solutions is infinite. The first system is merely 2 times the second system. If you solved the system by using elimination method, you would get 0=0 which is always true. If you put both into slope- intercept form you would get y=(-3/2)x+3 for both which means that in the plane they are the same line and therefore cannot ever intersect nor be parallel to each other.
