For f(x) plug in the number given into the x value of the equation. As an example A would be
f(-6) = 1 - 5 (-6)
Simplify: f(-6) = 1 - (-30)
Solve: f(-6) = 31
8x-8= 5x-35
8x-8=5x=-35+8
3x=-35+8
3x =27 then divide both sides by 3 and 27/3 is -9
But in the long run download Photo-math it is a HUGE help it will show you the steps too
