Answer:
234 students and 151 family members
Step-by-step explanation:
Let x be the amount of students and y be the amount of family members...
x+y=385
x=y+83
We can solve using substitution...
y+83+y=385
Combine like terms
2y+83=385
Subtract 83 from both sides
2y=302
Divide both sides by 2
y=151
x=151+83
x=234
There were 234 students and 151 family members.
