    I've already got part A... A = 9(x+23)/2 2A = 9(x+23) 2A/9 = (x+23) 2A/9 - 23 = x x = 2A/9 - 23

    ok so take the equation that is had from part a, and instead of the variable, substitute it 108 then solve, u get it now?

    the equation is x=2a/9-23 so 2x108=216 216/9=24 24-23=1 x=1

    So is it this? 108 = 9/2(x+23) 108 = 9(x+23)/2 216 = 9(x+23) 216/9 = x + 23 24 = x+23 24 - 23 = x 1 = x x = 1

    ok so we need to solve for n, this means we need to set an equation that solves for n so what we need to do is isolate the variable "n" so your steps are

    –np – 90 > 30 first add 90 to both sides -np>120 then you want to divide by p -n>120/p then finally u have to divide by -1 since there is an invisible 1 next to the p and we need to get rid of that negative n>-120/p is your final answer!

    I was taught that if you divided by a negative, the sign was flipped. Am I confused about that?

    yes whenever u divide anything my a negative it becomes the oposite sign, youre correc about that!

    So should the sign be flipped at the end in this?

    yes the answer is a negative fraction which is -120/p
