\(Let $f(x) = ax+b$, where $a$ and $b$ are real constants, and $g(x) = 2x - 5$. Suppose that for all $x$, it is true that $g(f(x)) = 3x + 4$. What is $a+b$?\)

Get rid of all the meaningless dollar signs, that would be an excellent place to start!

Ok, Im going to help Guest out a bit: Im going to try:

Let F(x)=ax+6 where a and b are real constants, and g(x)=2x-5 Suppose that for all x, it is true that g(f(x))=3x+4. What is A+B?

I would start by solving g(f(x)) and if you get a different thing than 3x+4, just set them equal to each other and simplify.
