Astore has thirty-five diet sodas, which is seven times the number of regular sodas they have. how many regular sodas do they have?

They have 5 regular sodas.

Here is an equation that you can use to solve this problem:
35 = 7 * x

The first step is to use inverse operations and divide both sides by 7, which gives you this.
5 = x

So, the answer is five. Good luck, and if you need any other answers, be sure to tell me!
