color(magenta)"k = -0.11111"

Explanation:

color(pink)("Subtract 3 on both sides:")

-9k+cancel3= 4
color(white)(aaa)-cancel3 color(white)(a) -3

3 cancels out on the left side, and when you subtract 3 from 4 on the right you get 1:

-9k = 1

color(blue)("Divide both sides by -9 to get k by itself.")

(cancel"-9"k)/cancel"-9"=(1)/-9

Now you are just left with k on the left side and -0.11111 on the right side.

Thus,
color(magenta)"k = -0.11111"
