okay so my question is 8-x/3=-10 i now that you would substract -8 from both sides but what do you do then

Algebra
the answer would be 15 becuase when you divide 45 by 3 you would get 15

Math(is this correct?)
yes it is

uhmm i think you would subtract 4 from both sides so that would just leave you with 3x 3x+4=193 -4 -4 3x= 189 then you would divide 3 from both sides which leaves you with 63 x=63 =] oh and make surewhen you do these promblems you go back and check it
