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:
x/2
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:
2x+3
2x+3
So x/2=2x+3.
Then solve for x.
x/2=2x+3
2*(x/2)=2*(2x+3)
x=4x+6
x-4x=4x+6-4x
-3x=6
-3x/-3=6/-3
x=-2
As a result, the number is -2.
I hope this helps!
