Answer 1

french alone = f
history alone = h
both = 8

f+8 - 10 = h+8
or
f-h = 8
and
f+h + 8 = 40
or f+h = 32
so
2f =40
f = 20
h = 12
so
f+8 = 28 study french or both
h+8 = 20 study history or both

Answer 2

french alone = f
history alone = h
both = 8

f+8 - 10 = h+8
or
f-h = 10
and
f+h + 8 = 40
or f+h = 32
so
2f =42
f = 21
h = 11
so
f+8 = 29 study french or both
h+8 = 19 study history or both
