How do I solve this absolute value inequality? Should I add two to both sides first?
| -3n | - 2 = 4

  • Math -

    Not inequality I meant equation.

  • Math -

    since |x| =
    x if x>=0
    -x if x<0

    so, either

    -3n >= 0 and
    (-3n) = 6 so n = -2


    -3n < 0 and
    -(-3n) = 6 so n=2
