Picking variables, x= how many snickers, y= how many reeses. The total count of candies is x+y=12.

The fat -----
Combined, the amount of fat is 70+26.5 grams. This is 96.5 grams of fat.

Use the variables and the fat content to account for the fat:
14*x+13.7*y=96.5

The system to solve is:
14%2Ax%2B13.7%2Ay=96.5
x%2By=12
The easiest path to continue from here is to multiply the second equation by 14, and then subtract from the first equation. This will lead you to a solution for y. Then continue solving.
