Let's do #5 *-*
We have \(\tt \color{red}{\dfrac{b}{47}= -2}\) To solve this you must:
\(\tt \color{red}{Multiply~47~on~both~sides~of~the~equation.}\)
So, now we have \(\tt \color{red}{\dfrac{b}{47}\times47= -2\times47}\)
Do you know how to simplify this? Once you do, you will get your answer :)

- anonymous

so do -2x47?

- sammixboo

Right

- sammixboo

And that's your answer for #5. Tell me what you got :)

- anonymous

b=(-94)

- sammixboo

Correcto *-*
Now let's do #4: \(\tt \color{red}{4= \dfrac{s}{-14}}\)
Do you have an idea on how to solve this?

- anonymous

i would do -14/4?

- sammixboo

Not quite, you would \(\tt \color{red}{multiply}\), since you are originally \(\tt \color{red}{dividing}\).

- sammixboo

So, \(\tt \color{red}{-14\times4}\)

- anonymous

-56

- anonymous

s=(-56)

- sammixboo

Correct again ^-^ #4 is -56.
Let's do #3: \(\tt \color{red}{\dfrac{t}{-3}=12}\)
Do you know what to do on this one?

- anonymous

12x-3?

- sammixboo

Right, which is?

- anonymous

t=-36

- sammixboo

Right *-*, so #3 is -36
Now for #2, we do the opposite since we are originally multiplying.
\(\tt \color{red}{7r=-56}\)
We have to \(\tt \color{red}{divide~7~on~both~sides}\). What do you think the answer is?

- anonymous

SO....-56/7

- sammixboo

Yeppers :)

- anonymous

UM...I GOT SUM REALLY LONG NUMBER

- sammixboo

You shouldn't. Make sure you type -56/7 and not 7/-56

- anonymous

i got -8.142857143

- sammixboo

Sure you typed everything correct?

- anonymous

yep stll got the long number

- sammixboo

You typed -57/7, not -56/7

- anonymous

X___x

- anonymous

I GOT -8

- sammixboo

^-^ It's ok. It happens a lot, and that is right, so #2 is -8

- anonymous

r=-8

- anonymous

i think ik #1

- sammixboo

What do you think it is?

- anonymous

y=-32

- anonymous

cause u remeber the teachers saying if the letter by itself it counts as a 1 in front of it

- sammixboo

Close, but not quite.
Now for #1, we have \(\tt \color{red}{-y = -32}\), since they are both negative, your answer should be positive

- anonymous

OH OK

- anonymous

y=32

- sammixboo

If y = -32, then we would have - - 32 = -32, which isn't right :P

- sammixboo

Right *-*

- sammixboo

Good job :)

- anonymous

YAY...i feel smart

- anonymous

i think i can do the other 16 by myself

- sammixboo

Okie dokie. Once you finish you can post it here and I can check it if you want.

- anonymous

ok
