1. 3x + 4 < 2x + 5
    3x - 2x < 5 - 4
        x < 1
HP : {x| x < 1 , x ∈ R}

2. 5x + 2 = -x + 14
    5x + x = 14 - 2
    6x = 12
      x = 2
HP: {2}

3. 6x - 3 = -2x - 27
    6x + 2x = 3 - 27
    8x = -24
     x = -3
HP : {-3}

4. x - 7 = -3x - 19
    x + 3x = 7 - 19
     4x = -12
       x= -3
HP : {-3}
