"negative" means less than 0, so 15 - 5n < 0 know where to go from here?

would you add 15 to the other side?
Vocaloid
  • Vocaloid
subtract
iwanttogotostanford
  • iwanttogotostanford
so we would then have -5n less than -15?
Vocaloid
  • Vocaloid
yes, do you know what to do next?

  • iwanttogotostanford
divide!

  • iwanttogotostanford
so would n=3?
Vocaloid
  • Vocaloid
almost but not quite so we have -5n < -15 divide both sides by -5 gives us n > 3 (remember, when we divide or multiply by a negative number, the inequality sign flips direction)
