3x+2x=-15
5x=-15
5x/5 = -15/5
x=-3
Numbers with the same variable can be combined, which would make you add 3x and 2x to give you 5x. then to get rid of the 5 in front of the x, divide BOTH sides by 5, the 5 is then divided out from the x, and -15 divided by three is -3

katovenus [111]

Answer: None of the choices

Step-by-step explanation:

1. It couldn't be integers (whole numbers positive or negative), because a cube couldn't have a negative volume.

2. It could be natural numbers, but the problem is, that a volume could have decimal values, for example, 3.62 meters cubed which a natural number doesn't support.

3. Set of whole numbers is the same as integers, so it can't be that.

4. None of the choices, which in my opinion is the correct one.

I'm not sure it is correct, but I hope I helped you!
