Answer 1

Hi,

Answer B

Explanation:

To solve the equation kx+12=3kx for x, you'll need to isolate x on one side of the equation. Here's how you can do that:

First, move all terms involving x to one side of the equation. To do this, subtract kx from both sides:

kx−kx+12=3kx−kx

This simplifies to:

12=2kx

Now, you have 12 on one side and 2kx on the other side. To solve for x, divide both sides by 2k:

`(12)/(2k) =(2kx)/(2k) \\`

This simplifies to:

`(12)/(2k) =x`

Finally, simplify further by dividing both the numerator and denominator by 2:

`(6)/(k) =x`

So, the solution for x is

`x=(6)/(k)`

In summary:

`kx+12=3kx\\\\12=3kx-kx\\\\12=2kx\\\\6=kx\\\\x=(6)/(k)\ (if\ k \\eq 0)`
