Define a variable, write an inequality, and solve the problem : Four less than nine times a number is greater than eleven more than two times the same number.

x > 15/7

Step-by-step explanation:

four less than nine times a number:

9x - 4

Eleven more than two times the same number:

2x + 11

Thus:

9x - 4 > 2x + 11

7x > 15

x > 15/7

I hope this helps you :)
