Evaluate the function for $x = -2a$ if $a = 3$ $$f(x) =-4x + 7$$.
We are given x and a, first lets solve the first problem, what does x equal when we sub the value of $a$ into it:
$$x = -2(3)$$

when they say 
x= -2a  they mean  x is the same as -2 * a (-2 times a)
if they tell you what a is  ("a"  is 3)
can you figure out what x is ?
