Answer:
15 students study math and not English
Step-by-step explanation:
lets take the # or people who study math but not English as "x"
so 90 students study math or English
25 students study English and not math
and
50 study both
since 90 students study math or English that is what our equation will equal.
so
25+x+50=90
25+50=75
75+x=90
subtract "75" from both sides:
x=15
