help?
In a certain county, the number of charter schools is 4 less than twice the number of alternative schools. We know that there are 48 charter schools in the county. How many alternative schools are in the county?
52
22
36
26
i tried 48 + 48 = 94 then going to 94  4 to get 90 but that's not an answer...???

Best ResponseYou've already chosen the best response.1ok, it also says that the number of charter schools is 48 so we have: c = 2a  4 48 = 2a  4 do you know how to solve for a now?

Best ResponseYou've already chosen the best response.0uh sorry you lost me, 2a would be 2*48 right? and that makes 94? but then take away 4 to get 90? but there is not an option for that

Best ResponseYou've already chosen the best response.1don't apologize, you're doing fine :) so 2a4+4 = 2a now we have 2a = 52 divide both sides by 2 to find a
