Question

14+3w=8w-3(w-4)

Answer 1

And what did you get? What did you do? Where did you have trouble?

Answer 2

i need step by step i dont know what to do

Answer 3

Know your order of operations?

Answer 4

PEMDAS

Answer 5

Yes. So, things inside ( ) happen first. (w-4) Well, it is a variable and a number, so nothing to do... Next is multiplication. Do you see anything that could be multiplied?

Answer 6

Well, exponents is next, but there were none, so I am skipping to multiplication.

Answer 7

i need you to draw me step by step

Answer 8

I'll help you, but I am not going to do your work for you.

Answer 9

ok

Answer 10

i have a headache trying to solve the same problem but i dont knnow to do it

Answer 11

Well, like I asked, do you see anything that can be multiplied?

Answer 12

-3and w

Answer 13

-3(w-4)

Well, the -3 is outside the ( ) so you need to distribute it to both the w and the -4. But good, you saw it. So just distribute it to both and what does the whole thing become?

Answer 14

so is it (-3x4)-3?

Answer 15

then

Answer 16

-3w-1

Answer 17

I KNEW IT YES

Answer 18

-3w is correct, but what is \((-3)\times (-4)\)?

Answer 19

12!

Answer 20

no the answer is 1 not 12 lol

Answer 21

i need step by step

Answer 22

If you are jumping ahead to the final answer, I don't know, I have not done the entire problem. If you are looking at the distribution part, XVas is correct, it is not -1 is is +12.

14+3w=8w-3(w-4) becomes: 14+3w=8w-3w+12

That is distributing the -3. Now, can you simplify it any more?

Answer 23

i dont understand never mind

Answer 24

Google it.

Answer 25

Just look up www.mathway.com ,

Answer 26

you can upgrade to steps if u want

Answer 27

For this part, it is the distributive law:

Answer 28

thanks guys

Answer 29

These things are applying the rules like that. So you distribute to get rid of the ( ). Then you can add or subtract and do algebra to move things from one side of the = to the other.
