Best ResponseYou've already chosen the best response.0I think there is something wrong with the question as appears to just have one half of the differential equation and has " and '  not sure if that should be something else. y5y+6y=x would mean y11y=x = 10y=x but as you have nothing it equals to it doesn't really help

Best ResponseYou've already chosen the best response.0Na dude, it's a differential equation, means you have to find such a function y=y(x) which satisfies it. y' and y'' are its derivatives.
