Number of questions worth 5 points = 10
Number of questions worth 2 points = 25
Further explanation:
The given system is a system of linear equations in two variables.
We will use the subsitution method to solve the system
Given equations are:

From equation no 1:

Putting x=35-y in second equation

Hence,
