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. 12 -12 2 -2

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

    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.

    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.
