Regularly 5036

Out of 129 1st-year students, 116 students go to lunch or dinner regularly, and 62 students go to one of these meals at most. At the same time, 46 students go to lunch more than to dinner. How many students go to lunch and dinner, how many go to dinner, and how many go to lunch?

Correct answer:

o =  54
s =  54
v =  8

Step-by-step explanation:


o+s+v = 116
o+v = 62
o = 46 + v

o+s+v = 116
o+v = 62
o-v = 46

Row 2 - Row 1 → Row 2
o+s+v = 116
-s = -54
o-v = 46

Row 3 - Row 1 → Row 3
o+s+v = 116
-s = -54
-s-2v = -70

Row 3 - Row 2 → Row 3
o+s+v = 116
-s = -54
-2v = -16


v = -16/-2 = 8
s = -54/-1 = 54
o = 116-s-v = 116-54-8 = 54

o = 54
s = 54
v = 8
