c.) 10
the positive integers are 10, 12, 13
Unequal means that the three numbers should be different.

unequal integers are whole numbers (integers) such as 5, 6, and 7, that are not the same (unequal) such that unequal integers combined to equal 35 cannot be 10, 10, and 5 because they are not all unequal. Thus there are many answers such as 1 + 20+ 14 equals 35 but we need the largest smallest integer so we have 10 + 11 + 14 = 35 because if we did 11 as the smallest we would have 11+ 12+12 = 35 and they would not be all unequal. Thus the answer is C, 10.

An integer is a whole number. So when is says "unequal" it is looking for whole numbers that are not the same.
example: 1, 3, 5 would be unequal
Example: 1, 1, 5 would have numbers that are equal so this would not work

x + x+a + x+a+1 = 35
3x + 2a = 35 -1
3x = 34 - 2a
x=(34 - 2a)/3
we can make (34 - 2a) dividable by 3 if a=2 (smallest value)
x=(34 - 4)/3
x=30/3
x=10

By brute force technique, I got 10 as the answer.
