Question

3+z=-19 true, false, or open

Answer 1

subtract 3 from both sides to get 3+z=-19 3+z-3=-19-3 z = -22 So it's only true when z = -22. This means that it's neither 100% true nor 100% false. So it's an open statement or sentence

Answer 2

First thing you would do is subtract 3 from both sides to get 3+z=-19 3+z-3=-19-3 z = -22 So it's only true when z = -22. This means that it's neither 100% true nor 100% false. So it's an open statement or sentence
