D.It is not a solution to either equation.

Sagot :

Answer:

Option D

Explanation:

The two equations given here are

a) 2x + 4y  = 4

b) 8 x + 2y = 4

On solving the above two equations we get

4 (2x + 4y  = 4) - Eq (1)

8 x + 2y = 4 - Eq (2)

The equation now is as follows -

8 x + 16y  = 16 - Eq (1)

8 x + 2y = 4 - Eq (2)

Substracting equation (2) from equation (1), we get -

8 x + 16y  = 16 - Eq (1)

- 8 x - 2y = -4 - Eq (2)

14 y = 12

y = 6/7

Hence the given value of X and Y i.e (-2, 3) is not the solution to any of the equation.

Hence Option D is correct
