we know that
A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form
or 
Let
x-------> the pressure in PSI
y------> the volume of the gas in cubic inches
In this problem we have the point 
so

Find the constant k

substitute the values of x and y


the equation is

therefore
<u>the answer is</u>

Answer: The number is 23
Step-by-step explanation:
Let x be the [number]
Rephrase the expression
a number increased by 11 is equal to twice the number decrease by 12
x+11=2x-12
Add 12 on both sides
x+11+12=2x-12+12
x+23=2x
Subtract x on both sides
x+23-x=2x-x
x=23
