Yeah but i dont know what "subject" in algebra to learn now... i know linear equations, equations without numbers and i have a basic understanding of the quadratic equation.

Inopeki, yes that's a perfectly fine piece of notation.
Like we all said yesterday, your enthusiasm is fantastic. Why don't you continue to work through the Khan Academy material? The best way to use to this site for mathematics is to come to use with specific questions you have.
This is not an ideal place for us to systematically teach you and nearly all of us here aren't here to do that anyway.

ok and this
3x+6=9 solve for x
Inopeki

remove 6 from both sides of =, get 3x=3, divide them both by 3 and you get 1. x=1

f(x)=x^2-3x+2, i have to put a number for x right?

nice so
1/(2x) - (3+x)/(x) = 2 solve for x

- this is in equation form but equation with fractional terms
