  1. |5x-4| +5 > 7

    |5x-4| > 2

    which means that  5x-4 > 2

    and also               5x-4 < -2

    solving the first one       5x-4 > 2

                                          5x > 6

                                             x> 6/5

    solving the second one    5x-4 <-2

                                          5x < 2

                                            x < 2/5


  2. |5x-4| > 2

    |5x-4| > 2 = |5x-4| > 6 = |5x| > 6 = 6/5

    |5x+4| > 2 = |5x+4| > -2 = |5x| > -2 = -2/5


  3. l5x-4l + 5>7

    5x+4+5>7

    5X+9>7

        -9  -9

    5X>-2

    5     5

    X>-2/5 i think thats how u solve it  

  4. use google's embedded calculator in their search engine
