Question:- Translate seven is greater than the difference of twice a number and nine into an inequality

 Solution:- Given we have to use inequality form 

According to question

7 > 2x - 9 

We can also find value of x 

7 + 9 > 2x 

16 > 2x

8 > x 

We can interchange but don't forget to change inequality

x< 8 

Now put 8 into above equation

7 > 2(8) - 9 

7 ≥ 7 is the required result
