just plug in the variables given for the equation @RltFalloutPlease

debbieg · Answer

Plug in the given values:
3x - y - 3z  = 3(-2) - (1) - 3(-2) = ???

What do you get?

jamierox4ev3r · Answer

if you want to find 3x-y-3z plug everything in and solve, as @DebbieG said; 
                              ^  ^    ^
                            -2  1   -2


Just a little visual up there of where exactly you would plug in stuff, but from here, it should be fairly easy to solve because there are no variables here
