Which of the following equations could you solve by first adding six and then dividing by negative three?

3x - 6 = -9
6 - 3x = -9
-3x - 6 = -9
x/-3 + 6 = -9

2: Which of the following expressions could be interpreted as "a number times negative seven added to five equals two"?

x - 7 + 5 = 2
5 + 7x = 2
-7x - 5 = 2
5 - 7x = 2

3: Solve -5 + w/3 = -1.

First

WAIT C

sophiaholder · Answer

Sorry didn't see the word negative. *facepalm*

welshfella · Answer

you would add 6  in order to remove numbers from one side of the equation

sophiaholder · Answer

What? hmm. That makes no sense. 1 should be c

jessie13 · Answer

never mind i did it, it was right i accidentally pressed D

welshfella · Answer

- and divide by -3 to isolate x

welshfella · Answer

@sophiaholder  please don't give direct answers

jessie13 · Answer

@welshfella  waht do u think?

sophiaholder · Answer

@welshfella I already aasked if she wanted me to explain them earlier. She just wants the answers

welshfella · Answer

C for 2 is wrong

welshfella · Answer

you  have a -7x and  + 5

welshfella · Answer

@sophiaholder  Nevertheless  its a violation of the CoC.

jessie13 · Answer

Wait which one is that? @welshfella

sophiaholder · Answer

@welshfella sorry. She probably already has the answers and just wants to check if others agree.

sophiaholder · Answer

@jessie13 do you still need help?

jessie13 · Answer

yes on 2 and 3

sophiaholder · Answer

Okay so on two, I am not exactly sure. I think it is C because it had -7 and a variable (x). And added to 5 could mean subtraction because subtraction would make the five negative which would add to -7. And equals two. I am not too sure though. I think you should go with what you think.

jessie13 · Answer

k what about # three?

sophiaholder · Answer

On three, you will have to solve it. Since I am not allowed to give you direct answers, tell me what you think you should do first.

jessie13 · Answer

Idk

sophiaholder · Answer

Okay so we want to get the w by itself.

sophiaholder · Answer

So we need to get rid of the numbers surrounding it.

jessie13 · Answer

C??

sophiaholder · Answer

Yes ;)

jessie13 · Answer

thanks!!!
