Because you and i made the same mistake, we only read the first part of the question and "ignore" the second sentence.

sum of three sides is less than 18 5+6+x<18 subtract 11 on both sides x<7 now it cant be 0 or a negative integer

well look if it will be less than 1 then sum of two sides wont be greater than the third side ;)

i think i understood it already see if the othe side is 1 then 5 + 1 would be equal to 6 right? since we need the third to be greater and not equal to the sum then we use 2 and 2 is greater than 1 so if we would put it in a situation where x = 2 then we'll get 5 + 6 + 2 < 18 13 < 18 5+6 > 2 11 >2 5+2 > 6 7>6 6 + 2 > 5 8 > 5

We must fulfill the second sentence criteria to find the range of values of x hence, the range would be 1<x<7
