Assuming the problem is asking you to solve for z, follow the rules of solving for a variable.
You need to isolate z. So, start by getting rid of the 10 that is on the same side as the z. How can you get rid of that?

- anonymous

Subtract?

- anonymous

Yep, exactly. Subtract 10 from both sides of the equation. Your equation should now look like this: \[-8= \frac{ z }{ -3 }\]

Let me know if you didn't get this.

- anonymous

If I ever have a problem like this will I always have to subtract a number in place of the 2 and 10?

- anonymous

Well, generally speaking, the first step in most problems like this is to subtract (or add) a number to both sides.
If your problem was \[12x-7=14\] you would first add 7 to both sides.

- anonymous

How do you know which one to add to both sides?

- anonymous

We have to find z now right?

Correct. So, to get the -3 out of the denominator, what do you need to do?

- anonymous

Multiply and thanks I got it now I kinda lost memory of how to do the problems thanks I finished the problem I'll show it to you so you can correct me if I made any mistakes

Oh wait a second! The way you typed your question is a little different from the way that you wrote it! So subtracting ten is not the first step! You'll get used to typing equations correctly eventually, but in this case your problem would look like THIS: (10+z)/-3

- anonymous

So, instead of subtracting 10 as your first step, you need to get rid of that -3 first.

- anonymous

Oh ok I'll do that

- anonymous

I subtract to do that right?

- anonymous

Nope, in this case because -3 is in the denominator, you need to multiply by -3.

- anonymous

So you should get \[-6=10+z\]

- anonymous

Is that right?

Do you have any tips for negative and positive signs cause I'm not good with those

- anonymous

You got negative 6 and I got positive and I forgot the rules for negative and positive signs

- anonymous

Okay negative an positive:
If the two numbers you are multiplying have the SAME sign, it is always a positive answer.
If the two numbers you are multiplying have DIFFERENT signs, it is always a negative answer.

- anonymous

Ok thank you now that I have multiplied 3 on both sides what do I do with the rest of the problem

##### 1 Attachment

- anonymous

Now it's time to subtract that 10 from both sides.

- anonymous

Like that?

##### 1 Attachment

- anonymous

Yep, exactly. So you now have \[-16=z\]

- anonymous

Thank you sooooo much for helping me I thought no one was THANK YOOUU and if you passed freshman year can you tell me some math subjects I should be ready for?

- anonymous

Oh wow um well get ready to do a lot of factoring. There is a ton of factoring stuff in Algebra.

- anonymous

Ok thanks

- anonymous

How can I become a fan of you

- anonymous

If you roll your mouse over my profile, a box will pop up and there will be a button on the bottom that says become fan.

- anonymous

I'm on my phone when I get on my laptop till do it that's for the help :)

- anonymous

I appreciate it! Good luck with the rest of your math!
