Help me solve this problem please, I have tried so many time.I can not seem to get the problem right.
x +12 <-8 or x+12>2
x+ 12 < -8 =x +12 > 2
x =4 > -10 is this right

  • algebra -

    x +12 < -8
    Subtract 12 from both sides.
    x < -20

    x + 12 > 2
    x > -10

    Both inequalities cannot be true at the same time, for obvious reasons.

  • algebra -

    since the operator was "OR"
    the solution is
    x < -20 OR x > -10

    had the operator been "AND" there would have been no solution.
