Differential equation
A first order linear equation in the form y′+p(x)y=f(x) can be solved by finding an integrating factor μ(x)=exp(∫p(x)dx) (1) Given the equation (x+4)^2y′+5(x+4)y=16 find μ(x)= I found it to be e^(5ln(x+4))which is

2x + 3y = 78 How do i solve for x and y? 2x=78 78/2=39 so x=39 3y=78 78/3=26 so y=26 Can't be, because 2(39)+ 3(26) does not equl 78 You need TWO equations when you have TWO variables, such as x and y. It can't be done with one
