12 - 5x - 4kx = y.....subtract 12 from each side
-5x - 4kx = y - 12....factor out x on the left
x(-5 - 4k) = y - 12 ...divide both sides by -5 - 4k
x = (y - 12) / (-5 - 4k) or x = (-y + 12) / (4k + 5) <==
[tex]12-5x-4kx=y :x[/tex] 

[tex]-5x-4kx=y-12[/tex] 

[tex]-x(5+4k)=y-12 [/tex] 

[tex]-x= \dfrac{y-12}{5+4k} [/tex] 

[tex]x=- \dfrac{y-12}{5+4k}[/tex]
