3kx - 2k = 4 - 6x

 

3kx = -6x      and   -2k = 4

3k = -6          and     k = -2

  k = -2

k(3x-2)=4-6x        divide both side by (3x - 2)

k =(4 - 6x) / (3x - 2)

k =-2(3x - 2) / (3x - 2)

k = -2

I'm gonna just do a different method if ya don't mind.

\(k(3x-2)=4-6x\)

\(k(3x-2)=-6x+4\)

\(k(3x-2)=-2(3x-2)\)

\(k = -2\)
