    It's a really quick problem, so just lemme know soon whether you wanna work it out with me. I'll explain it to ya once you let me know you're here.

    Awesome. Alright, we have two ways of doing this. I'll show you the longer, but safer, method. First thing we want to do is get rid of those parentheses. Any guesses on how would we do that?

    Okie dokie, not a problem. Basically if you ever want to get rid of parentheses that have a number on the outside stuck directly to them, you distribute the 'number stuck outside' to everything inside the parentheses. -6 (x - 4) =6 So what number is stuck to the parentheses on the outside?

    Close, but it's not just a regular 6. There's something special about that 6 (it's really important).

    The x is actually inside the parentheses. Here's a hint: -6 (x-4)=6 So what number is out there all by itself on the left side?

    Exactly! Now, are you pretty familiar with distributing? You'll have to distribute the -6 to the two numbers inside the parentheses.

    Whenever you're done with the distribution, lemme know what you got. After that, we have like two or three more quick steps and we should be done. :D

    Here's the problem again so that you don't have to scroll: -6 (x - 4) =6

    I'm afraid not. I got a non-fraction answer. Can you show me what you got for your distribution on -6(x-4) ? That part is important to do before we do anything else. Hint: Be very careful with your signs.

    Just to be safe: do you know what happens when you do a negative times a negative?

    Exactly! So that's correct for the -4 * -6 part of the problem. But I think you forgot to do -6 times x. What does that give you?

    Remember: -6(x-4) Means: -6 times x ??? -6 times - 4 The ??? gets replaced with plus or minus depending on whether the -6 and -4 give a positive answer. Since we know it's positive, we know it's: (whatever -6 times x is) + 24 = 6 So what do you get if you do -6 times x?

    Since I've gotta go work on my own HW pretty soon, I'll go ahead and let ya know: -6 times x is -6x. So... how should our equation look for now? (Don't solve it yet, just tell me what it should look like).
