Let x and y be the numbers of questions worth 5 and 2, respectively. There are a total of 29 questions which means that x + y should be 29. The equations that best describe the conditions are,
x + y = 29
5x + 2y = 100
Solving for x and y gives x = 14 and y = 15. Thus, there are 14 and 15 questions worth 5 and 2, respectively.
Answer:

Answer:
there are two ways we can solve this problem the first way is in x-form and the second way is in y-form I will give you the answer for each of the ways.
Step-by-step explanation:
x-form: x=37-3y
y-form: y=37/3 - x/3
hope this helps if this was not the way you wanted me to solve it please let me know and I will do it the way you want me to do it.
