Final answer:
The largest whole number x could be so that 9+x is larger than 2x is 3.
Step-by-step explanation:
The table below shows the values of 9+x and 2x for different values of x:
x9+x2x090110221143126
From the table, we can see that the largest whole number x could be so that 9+x is larger than 2x is 3. For x=3, 9+3=12 is larger than 2x=6.
