Answer 1

D is answer as the answer comes in variable A,B,C potions are not correct

Answer 2

Answer:

OPTION D

Step-by-step explanation:

3 x - y = 12

We need to find the value of 8 x 2 y

The value of the given expression cannot be found unless by the trial and error method .

if we want to find the exact value the only way which will be possible is to trial and error .

But with the given information :

If we try to find the value we will end up expressing y in terms of x or we will end up expressing x in terms of y .

Hence we cannot find the value of x and y if another equation of x and y is not provided to us.

Thus answer is OPTION D.
