Answer 1

Answer:

13

Step-by-step explanation:

1. Find the two equations

Descriptive: x

Multiple Choice: y

x+y=24 (total amount of questions)

3x+y=50 (total amount of marks)

2. Solve for x

y=50-x

3x+50-x=24

2x=-26

x=-13

-x=13, or x=13

3. Solve for y

13+y=24

y=24-13

y=11

4. Check

13+11=24 √

39+11=50 √
