PLEASE HELP URGEN

A row operation is performed on a matrix as shown below.

I 2 -1 1 I 4 I. I 0 -3. x I -18 I
I 1 1 1 I 11 I > I 1. 1. 1 I 11 I
I 4. -2 2 I 5 I. I 4 -2 2 I 5 I

What is the value of x?
a. -2
b. -1
c. 0
d. 3

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.
