    good,now divide by -4 remember to flip the sign,as u are dividing by a negative number so < becomes >

    Like this: First Part: X >-3/4 Second Part: x< = 23/4 Interval Notation: -3/4 < x < 23/4

    let me give example: 2<=x<6 [2,6)

    So... is it: [-3/4, 23/4) ?

    so, -3/4<x<=23/4 will give u (-3/4,23/4]

    as = part is with 23/4,u have ] bracket with 23/4

    Okay I got it. I put the bracket for -3/4 before. That's where I went wrong.
