Answer:

Steps :
1. Create an equation
If x-4=0 and y-10.4=0, then x - 4 = y - 10.4

2. Isolate variable X by adding 4 to both sides

3. (Optional) Check Answer by plugging given values into the equation

4 = 4 is a true statement
Since you know it should be between 3 and 4, it should be 3. something. So now, just go up to 1/2, or 1/3, or etc until you know it's the product of 9 and 12. I have figured out that it would be 3 and 1/10 and 3 and 2/10. I have checked, and they both have the product of 9 and 12. And it is between 3 and 4.
