Answer:

  a = -19

Step-by-step explanation:

In the first set of equations, subtract 4 times the second equation from the first.

  (x -8y) -4(5x -2y) = (-3) -4(4)

  -19x = -19 . . . . simplify

Comparing this to the equation ...

  ax = -19

we see that they will have the same solution when a = -19.
