Answer:
The solution is

Step-by-step explanation:
The given equations are

and

The graph of the two equations intersects at
as show in the graph in the attachment.
The point of intersection of the two graphs is the solution to system of equations.
Hence the solution is

Answer:
28
Step-by-step explanation:
x = 2 point questions, y = 3 point questions
x + y = 40
2x + 3y = 92
Solving this we get x = 28, y = 12 so the answer is 28.
