Respuesta :
x=number of 3 point questions
y=number of 5 point questions
The total number of questions was 24.
x+y=24
3x+5y=100
Multiply the first equation by negative 3:
-3x-3y=-72
3x+5y=100
Add the equations together:
2y=28
y=14
Plug 14 for y into the first original equation:
x+y=24
x+14=24
x=10
This indicates that the test contained 10 3-point questions and 14 5-point questions.
