Answer:
b. infinite solutions
Step-by-step explanation:
Therefore, the graphs are the same.
If the graphs of the equations are the same, then there are an infinite number of solutions that are true for both equations.

Step-by-step explanation:
The question in English is
In the ninth grade, 62.5% of girls and 80% of boys passed the mathematics course, while 87.5% of girls and 60% of boys passed the history course. Calculate the number of students in the classroom, if the total number of passes is 26 in both subjects
Let
x ----> total girls in the classroom
y ---> total boys in the classroom
we know that
mathematics course
-----> equation A
history course
----> equation B
Solve the system of equations by graphing
Remember that the solution is the intersection point both graphs
using a graphing tool
The solution is the point (16,20)
see the attached figure
therefore
In the classroom there are 16 girls and 20 boys
