Your inequality is (x being number of people): 175≥35+10x+3x
First, combine like terms so your new inequality is: 175≥35+13x Then subtract 35 from both sides which makes it: 140≥13x then divide 140 by 13 making it: <span>10.769≥x </span>But because you can't have .769 of a person the actual answer is 10 then you have to subtract 1 because he isn't including himself and there is the answer!: 9≥x
