Joshua Huffman · 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

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
