First you want to figure out 196- 16. That will give you 180. Now divide 180 by 2, which is 90. So the numbers in the parentheses have to add up to 90. Now you want to add 7 and 5. This will give you twelve. Then subtract 12 from 90 to get 78. 78 divided by 3 will give you nine. 78 divided by 3 is 26, so y would be equal to 26.
