What is the solution to the system? x + 3y - z = 6 4x - 2y + 2z = -10 6x + z = -12 a) (-4, 0, 12) b) (0, -2, -12) c) (-3, 5, 6) d) (2, 1, -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.

the answer to your question a or b but i am pretty sure it is b. i hope this : )
