78 = -6 (p - 4)i don't understand it

Distribution is one of the most important terms of math you need to know.

Distributing, in this case, is when you take the -6 and multiply the terms in the parenthesis.

When you do that. You’ll get -78 = -6p+24.

*Remember: a negative times a negative is always positive. A positive times a negative is always negative. If you need more help with this tip, please feel free to reply if you need any better tips and tricks.

Now, you’re going to solve -78-24 (since you switch the sign when you bring one term to the opposite of the equation).

Then you’ll have -102 = -6p

Lastly, instead of multiplying, you divide -102 by -6.

Your final answer should be 17 = p (or flip it to make it p = 17).
