Question 620135
Which number is not a solution of either x < -3 or -x < 3?


x < - 3 includes all numbers less than - 3


- x < 3 becomes x > - 3 ---- Dividing by - 1 and switching inequality sign


We now have: x < - 3, or x > - 3


The number, or integer that's not a part of this solution is {{{highlight_green(- 3)}}}
