we are given the ordinary differential equation of dy/dx = 2y+1. The ODE is variable separable which means x and y can be grouped altogether explicitly. In this case, the equation becomesdy / 2y + 1 = dx
1/2 ln (2y + 1) = x + ln Cln (2y + 1) = 2x + ln C2y + 1 = C e 2x y = (C e 2x - 1)/2
The ODE y' + xy = x can be grouped into y' + x(y-1) = 0 'y' / y-1 = -xThis is variable separable
Hi,
(9n + 4) - (-12n - 7)
9n + 4 + 12n + 7
<em>=</em><em> </em> 21n + 11
