x and y are integers. x + y < 11 , and x > 6. What is the smallest possible value of x - y ? Choose the most appropriate option:
A) 1  B) 2  C) 4  D) -2  E) -4
Because x &amp; y are integers, the two equations can be simply written as :   x+y&lt;= 10 --- eq. 1   x&gt;= 7 ---- eq. 2   For smallest value of x-y, x has to be the smallest whereas y has to be the largest.   From the above eq. 2, smallest value of x = 7   Plugging it in eq. 1: 7+y&lt;=10, or y&lt;=3   Therefore, largest value of y=3 &amp; smallest values of x=7   x-y = 7 - 3=
