well you know that the number is going to be 2*48-4.
Can you solve it from there?
OpenStudy (anonymous):
That 92 which is not one of the choices

@kimbllse777 I think you got a little mixed up! So the question boils down to 2x -4 = 48.
Do you know where to go from there, or shall I explain? :)

so it says exactly "the number of charter schools is 4 less than twice the number of alternative schools. We know that there are 48 charter schools"
OpenStudy (anonymous):
4 less than 2 ^ alternative = charter
OpenStudy (anonymous):
so x = alternative
OpenStudy (anonymous):
so 4 - 2x = 48
