1. The problem statement, all variables and given/known data Solve the inital value problem for y(x); xy′ + 7y = 2x^3 with the initial condition: y(1) = 18. y(x) = ? 2. Relevant equations dy/dx +P(x)y=Q(x), integrating factor=e^∫P(x) dx 3. The attempt at a solution Multiplied all terms by 1/x to get it in correct form dy/dx+7y/x=2x^2 integrating factor=e^∫7/x dx=x^7 here is where i get lost do i multiply everything back into the original eq. or am i already off. I am not getting the correct answer.
