Answer:
The answer to your question is: 35 questions worth 2 points and 15 questions worth 3 points.
Step-by-step explanation:
Data
Number of questions = 50
Total points = 115
x = questions worth 2 points
y = questions worth 3 points
Process
write to equations
(1) --------------- x + y = 50
(2) -------------- 2x + 3y = 115
Solve them by substitution
x = 50 - y
2 (50 - y) + 3y = 115
100 - 2y + 3y = 115
3y -2 y = 115 - 100
y = 15
x = 50 - 15
x = 35
