ok here are some of my problems. I dont understand how to add numbers with letters. or multiply them with eachother....

If you really don't know how to work with variables, etc, then an explanation of how to solve the linear inequalities you've posted won't make much sense, I'm afraid. You first need to learn the background information.

Since we cannot provide the necessary hours of classroom instruction, please

**study some online lessons**. At a minimum, you should learn about negative numbers, absolute value, factoring numbers, variables, exponents, the order of operations, evaluation, and basic polynomials. Then study how to solve linear equations. At that point, you'll be ready to study linear inequalities.

Please allow yourself a week or two, at a minimum, for studying these topics!
