Given any positive even integer, x, the positive difference between the smallest odd number greater than 7x - 2 and the largest odd number less than 3x + 5 can be written in the form ax + b. What is a + b?
if x is 2,
\(7x-2=12\) so 13 for the large one
\(3x+5=11\) so 9 for the small one
either a is 2 and b is 0 or a is 1 and b is 2, so i guess 2 or 3!
Hope this helps!
