    ok so you want to leave p one one side of the inequality so how would you do that for: 4p + 1 > -11

    divide -11 by 1 so 4p<1?

    no, you would do: 4p + 1 > -11 4p + 1 -1 > -11 -1 4p > -12 4p/4 > -12/4 p > -3 do you understand?

    ok so here you don't switch the sign because you are not dividing the number by a negative number so the answer would be: p < 6 does that make sense?
