Explanation:

Let the number be n
So, according to the statements, we can write the equation = 3 – n².
Let the number be n
So, the equation is 2n² – 5.
Let the number be n
So, the equation is 5 – 2n².
Let the number be x
So, the equation is 4 – 2x.
Let the number be n
So, the equation is 7(n + 1).
Let the number be n
So, the equation is n² + 6.
Let the number be n
So, the equation is 2(n + 6).
Let the number be n
So, the equation is n² – 3.
