For this problem, let's start by calling the number "x".
The first part says that the "quotient of a number and 2", so this means x is divided by 2, like so:
The second part mentions that the previous is "the same as a number doubled and 3." What this means is that x is multiplied by 2 and 3 is added to the result like this:
Then solve for x.
As a result, the number is -2.
I hope this helps!
