Two consecutive even integers have a sum of 42 . find the integers.

Consecutive means 2 numbers next to each other

so let x equal our first number
and to get the number next to it, we simply add 1
so.. x + (x+1) = 42

combine terms and subtract 1 from each side
2x = 41

divide each side by 2
x = 20.5

I'm pretty sure it's b). i try drawing the functions out and b is the one that stands out or isnt a "line"
