- 5.5 seem, in case you artwork it out in demanding words ... 3 cases x provides you with about -9. Plus y (say 2) makes it about -7. for this reason 3x + y = about -7 Then z = say -2. and a pair of cases y is about 3. then -2 +3 is a million. Then divide -7 through 1 million = -7. So the answer should be about -7. for this reason the answer -5.5 is authentic
