If f(x) = 5x – 3 and g(x) = 4x + 7, what is f(g(x)) ?

$$\Large \color{MidnightBlue}{\Rightarrow f(4x + 7) }$$ $$\Large \color{MidnightBlue}{\Rightarrow 5(4x + 7) - 3 }$$

You basically have to think that if you are multiplying a number by 5 and adding three, then you'll multiply g(x) by 5 and add 3.
