Here is an example:
Eight more than a number x is less than 2 times the number.
8 more is 8 +
your number is x so now you have 8+x (or x+8)
Less than is the < symbol. > is the greater than symbol)
2 times the number is 2x.
8+x < 2x
Also, x+8 < 2x is another way you can write said problem.
Apply this information to your current problem.
