Answer 1

@ivettef365, that's actually wrong. You need to consider something first. Since first you need to isolate the variable, you subtract 7 from both sides and get\[\left| x \right|<-3\]But that's impossible, because absolute values are always positive, so the answer is no solution, or the null set.
