Don't you just plug in 8 for x?
3-5(8) = 3 - 40 = -37

3 - 5(8) = 3 - 40 = -37
"For x = 8" means you're plugging in 8 for the x in the equation and solving.

What they want you to do is find out what 3-5x is equal to; given that x=8. So you plug in what X is into your equation.
3-5(8)
Multiplication comes first if you remember. So:
3-40
3-40 = -37
