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.

If 3, x, y, -9 are in A.P, find the values of x and y.​
Serggg [28]

Answer:

  • x = -1
  • y = -5

Step-by-step explanation:

The common difference (d) can be found using the first and 4th terms:

  a1 = 3

  a4 = a1 +d(4 -1)

  -9 = 3 +3d . . . . . simplify

  -3 = 1 + d . . . . . . divide by 3

  -4 = d . . . . . . . . . subtract 1

Then ...

  x = a1 + d = 3 -4 = -1

  y = x + d = -1 -4 = -5

The values of x and y are -1 and -5, respectively.
