    Looks like I'm getting 312 after doing that. How about you?

    Great, so I guess we are at 312 = k x 13

    Step 1: Simplify both sides:\[6 × 4 × 13 = k × 13 = 312=13 \times k\]

    Step 2: Flip the Equation:\[312=13\times k~becomes~13\times k=312\]

    Right! So, we know what 13 times k is, how could you find k by itself? :)

    Step 3: Divide both sides by 13:\[\frac{ 13\times k }{ 13 } = \frac{ 312 }{ 13 }\]

    Hey, look! There's a great idea right there. :) Just divide both sides by 13. This leaves us with k.

    Yep, from what you started saying in the beginning, it seems like you have the basic ideas in place. With some more practice, you'll be all set.
