Solve 2x+9 greater or equal to 5 and 2x-13greater or equal to 9 what is the solution? I have x=-2 and x=2 how do I write this {x x> what?

  • algebra help bad!!!! -

    2x + 9 ≥ 5
    2x = -4
    x = -2

    2x-13 ≥ 9
    2x ≥ 22
    x ≥ 11

    Or, to actually answer the question,

    x ≥ -2 and x ≥ 11

    Since any x ≥ 11 is also x ≥ -2, the only solution is x ≥ -2.

    {x:x ≥ -2}
