What is y variable?

2x - 3y = 9

x = 2y + 2

Step-by-step explanation:

              x = 2y + 2

              2y + 2 = x

            -x + 2y = -2

            2(-x + 2y) = 2(-2)

           -2x + 4y) = -4

Hence, the value of y is 5.

Hoped this helped.

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.
