Math quick check thx
posted by Dam on .
Out of 42 kids in a class twice as many failed Ela as math,4 failed both. If 7 failed neither,
find how many failed each subject.
I made a venn diagram the middle part of the venn diagram would be 7 and the math part would be 13 and the ela part would be 26. How do i check this?

Math failed:
1,2,3,4,5,6,7,8,9,10,11,12,13
Ela failed:
10,11,12,13,14,...,33,34,35
Neither: 36,37,38,39,40,41,42
