    look at what across did above Evaluate means "plug in" the numbers (values) given for each letter (variable) so put 3 where the x is and put -2 where the y is tell me what you get

    \[3-2(-2) gives you 3-(-4) =7\]

    "Evaluate x - 2y when x = 3 and y = -2" I'm guessing it's the terminology that is throwing you off "Evaluate" means put the given numbers in there proper place. if x=3 put a 3 where the x is if y=-2 put a -2 where the y is show me what you get just by doing that, don't try for the final answer right away. step-by-step, remember?
