Answer:
[tex]x=6/k[/tex]
Step-by-step explanation:
we have
[tex]kx+12=3kx[/tex]
Solve for x
That means----> isolate the variable x
Subtract [tex]kx[/tex] both sides
[tex]kx+12-kx=3kx-kx[/tex]
[tex]12=2kx[/tex]
Divide by [tex]2k[/tex] both sides
[tex]12/2k=2kx/2k[/tex]
[tex]6/k=x[/tex]
Rewrite
[tex]x=6/k[/tex]
