Answer 1

Answer:

OPTION D

Step-by-step explanation:

3 x - y = 12

We need to find the value of 8 x 2 y

Unless by trial and error method we cannot find any value of the expression.

If we attempt so , then we will end up finding the expression in the form of x or in the form of y .

However the exact numeric value cannot be determined.

Hence we can say that the answer is OPTION D.

Answer 2

$\huge{\bf{Given}}$ :- 3x-y=12

$\huge{\bf{To\:Find}}$:-

Value of 8x2y .


$\huge{\bf{solution}}$:-

Given that 3x-y=12

$\huge \: \sf \: option \: d$



The answer to this question is that the value cannot be determined from the information given.

This can be done by using hit and trial method.

By that method, we can calculate the value of x and y, which will be different for different supposition .

So, using the equation given, we cannot determine value of 8x2y as the answer would be different for all our assumptions.
