Question

If 3x−y=12, what is the value of 8x/2y?
A) 21^2
B) 4^4
C) 8^2
D) The value cannot be determined from the information given.

Answer 1

Answer : (D) The value cannot be determined from the given Information,

Solution :

The given Equation is Linear Equation with 2 variables, So there are infinite number of solutions for x and y,

Such as :

(1) x = 5, y = 3,
(2) x = 6, y = 6,
(3) x = 7, y = 9,

So, There are infinite solutions, With keeping this in mind, We can say that, There is no definite answer for 8x/2y or simply 4x/y,

Because of many solutions !.

so there must be another equation to get the answer !.

Conclusion : Extra Information is required,

Therefore : With a single linear equation with 2 variables of having many solutions, We can't get a definite value of their variables and hence extra information is required !.

Hope you understand, Have a great day,
