Answer:

  A. `x= 0`, `y= (3)/(2)`

Step-by-step explanation:

Dividing the first equation by 4 gives ...

  x = 0

Substituting that into the second equation gives ...

  3·0 +6y - 9

  y = 9/6 = 3/2 . . . . divide by 6, reduce the fraction

The solution of the set of equations is ...

  x = 0, y = 3/2
